Local privilege escalation and memory corruption in the Linux kernel process-creation path arises because copy_process() takes the wrong error-exit label after futex_hash_allocate_default() fails, releasing tasklist_lock and siglock that were never acquired. This lock imbalance can corrupt kernel synchronization state on the fork error path, with a potential for kernel crash or exploitation to gain elevated privileges. No public exploit identified at time of analysis and EPSS is low (0.17%), consistent with a subtle, hard-to-trigger error-handling defect rather than a widely-weaponized bug.
Out-of-bounds memory access in the Linux kernel's in-kernel SMB/CIFS client (smb2_compound_op() in fs/smb/client) stems from wrong index references when iterating over compound SMB2 response buffers; a computed index at or above MAX_COMPOUND drives reads/writes past the response array. A machine mounting a share from a malicious or compromised SMB server can have its kernel process attacker-influenced compound responses, leading to memory corruption, denial of service, or potential privilege escalation. It carries a CNA-assigned CVSS 9.8, but there is no public exploit identified at time of analysis and EPSS is very low (0.19%, 8th percentile), so real-world exploitation pressure is currently minimal.
Privilege escalation and host memory corruption in the Linux kernel's i40e Intel Ethernet driver allows a malicious or buggy SR-IOV virtual function to send a crafted 'config queues' mailbox message with an out-of-range channel index, causing out-of-bounds access to the vf->ch[idx] array in i40e_vc_config_queues_msg(). Exploitation crosses the VF-to-host trust boundary (CVSS scope change) and can disclose or corrupt host kernel memory. The issue is fixed upstream across multiple stable trees; no public exploit and no CISA KEV listing exist, and EPSS is low (0.20%, 10th percentile), indicating no public exploit identified at time of analysis.
Local privilege escalation and memory corruption in the Linux kernel's fbcon (framebuffer console) subsystem stems from integer overflows in fbcon_do_set_font() when computing font buffer sizes from user-controlled parameters. A local, low-privileged attacker who can invoke the font-setting ioctl can trigger undersized allocations followed by heap buffer overflows during font data copying, potentially achieving code execution in kernel context. EPSS is low (0.16%, 6th percentile) and there is no public exploit identified at time of analysis; the fix has been merged and backported across stable kernel trees.
Local privilege escalation via memory corruption in the Linux kernel's iommufd subsystem allows a low-privileged local user to trigger a use-after-free by racing the abort path of IOMMU object allocation. Because fput() defers file release to a workqueue while the code immediately kfree()s the tied iommufd_object, the deferred release() decrements a users refcount on already-freed memory, corrupting the slab. Only pre-release 6.17-rc kernels are affected; EPSS is 0.10% (1st percentile) and there is no public exploit identified at time of analysis.
Out-of-memory denial of service affects applications that use the Go library github.com/nwaples/rardecode 2.1.1 and earlier to unpack RAR archives: a crafted archive can declare an oversized dictionary (window) size that the decoder allocates without enforcing a per-call bound, exhausting memory and crashing the process. Exploitation requires the target application to open the attacker-supplied archive (CVSS UI:R); no credentials are needed on the attacker side (PR:N), and the impact is availability-only (C:N/I:N/A:H, CVSS 6.5). Risk is genuine but moderate: EPSS is 0.37% (29th percentile), there is no CISA KEV entry, and no public exploit code has been identified at time of analysis - deployments that never ingest externally controlled RAR files are effectively unaffected.
Kernel-level memory corruption in the Linux kernel's rxrpc/RxGK subsystem allows an out-of-bounds access when the rxgk_yfs_decode_ticket() function parses an authentication response packet. The flaw stems from an unchecked unsigned subtraction ('ticket_len - 10 * 4') on attacker-influenced length data, which can underflow and drive an out-of-bounds write (CWE-787). It affects Linux 6.17 release-candidate kernels (rc1 through rc6); there is no public exploit identified at time of analysis, and EPSS exploitation probability is very low at 0.13% (3rd percentile).
Local privilege escalation and kernel memory disclosure in the Linux kernel's GPIO ACPI subsystem (gpiolib) affects development builds 6.17-rc1 through 6.17-rc6, where an uninitialized acpi_gpio_info structure is passed to __acpi_find_gpio() and its stale info->quirks field is later consumed in acpi_populate_gpio_lookup(). The regression, introduced by commit 7c010d463372, breaks the i2c_hid_acpi driver (probe fails with -EINVAL / 'has not been provided an Int IRQ') and causes the kernel to act on uninitialized stack memory. No public exploit identified at time of analysis, and EPSS is low at 0.14% (4th percentile), consistent with a hard-to-weaponize local memory-safety regression confined to release candidates.
Improper authorization in Casdoor (an open-source Identity and Access Management / SSO platform) versions 2.26.0 and earlier lets a remote authenticated administrator of ANY organization escalate beyond their tenant boundary. Because the permission-verification module and the organization/application editing interface fail to enforce object-level scope, a low-trust org admin can bypass access controls simply by concatenating/manipulating URLs after login to read and modify resources belonging to other organizations. A public technical writeup/PoC gist exists; it is not listed in CISA KEV and EPSS is low (0.61%, 45th percentile), so exploitation is plausible but not confirmed in the wild. Fixed in v2.63.0.
In the Linux kernel, the following vulnerability has been resolved: blk-mq: use quiesced elevator switch when reinitializing queues The hctx's run_work may be racing with the elevator switch when. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. This Use After Free vulnerability could allow attackers to access freed memory to execute arbitrary code or crash the application.
A logic error in the Linux kernel's device mapper thin pool module causes infinite loops and system hangs when metadata commits fail. The vulnerability affects Linux kernel systems with dm-thin storage pools; when a commit fails during btree metadata operations, the pmd->root pointer is not properly restored to the last valid transaction state, causing subsequent read operations to traverse a corrupted btree structure. An unprivileged local attacker with access to the system can trigger this denial of service condition, resulting in kernel softlockups and system hangs. While no public exploit code is widely distributed, the vulnerability is straightforward to trigger through storage I/O operations on affected systems.
A null pointer dereference vulnerability exists in the Linux kernel's WiFi mac80211 MLME (MAC Layer Management Entity) implementation that crashes the kernel during WiFi association tracing when an AP connection without link 0 fails. The vulnerability affects all Linux kernel versions with the vulnerable code path in the mac80211 wireless driver subsystem, allowing a local authenticated attacker to trigger a denial of service condition. The EPSS score of 0.01% indicates this is rarely exploited in practice, though patches are publicly available from kernel.org.
A resource leak vulnerability exists in the Linux kernel's mpt3sas SCSI transport driver where the sas_rphy_add() function can fail without properly freeing allocated resources, leading to a NULL pointer dereference and kernel crash during device removal. This affects Linux kernel implementations across multiple versions that use the mpt3sas driver for SAS (Serial Attached SCSI) HBA management. An unprivileged local attacker with sufficient privileges to trigger transport port operations can cause a denial of service by inducing a kernel panic, though the low EPSS score of 0.01% suggests exploitation is not practically demonstrated in the wild.
An information leak vulnerability exists in the Linux kernel's TIPC (Transparent Inter-Process Communication) subsystem within the tipc_topsrv_kern_subscr() function. The vulnerability occurs due to incomplete initialization of the sub.usr_handle field, leaving four bytes uninitialized when setsockopt() is called with SOL_TIPC options, allowing kernel memory contents to be leaked to user space. This affects Linux kernel versions including 6.1-rc1 and potentially others; while the EPSS score is extremely low at 0.01% percentile, the vulnerability requires local access and low privileges to trigger, making it a lower-priority but real information disclosure issue that has been patched by multiple vendors.
A null pointer dereference vulnerability exists in the Linux kernel's block layer (blk-mq) memory allocation path that can be triggered by a local, low-privileged user to cause a denial of service. The vulnerability affects Linux kernel versions including 6.1-rc1 and potentially other versions where a failed memory allocation during block queue tag initialization leaves a dangling pointer that is later dereferenced during cleanup. While the EPSS score is low (0.02%, percentile 4%), the vulnerability is straightforward to trigger under memory pressure conditions, requires only local access with minimal privileges, and has vendor patches available.
A memory leak vulnerability exists in the Linux kernel's test_firmware module initialization function (test_firmware_init) where allocated memory for test_fw_config->name is not properly freed when misc_register() fails. This affects all versions of the Linux kernel with the test_firmware module compiled, allowing local authenticated attackers to exhaust kernel memory and cause a denial of service. The vulnerability has a patch available from the Linux kernel maintainers, with an EPSS score of 0.01% indicating very low real-world exploitation probability despite the moderate CVSS score.
A memory corruption vulnerability exists in the Linux kernel's MSM display port driver that occurs when more than eight display bridges are connected, allowing local attackers with low privileges to corrupt kernel memory beyond a fixed-size array. The vulnerability affects Linux kernel versions up to 6.1-rc2 and requires local access to exploit, with no known active exploitation in the wild (not in KEV) and a very low EPSS score of 0.02% indicating minimal real-world exploitation likelihood.
A resource leak vulnerability exists in the Linux kernel's FSL PAMU (Freescale Peripheral Access Management Unit) IOMMU driver where the fsl_pamu_probe() function fails to release IRQ and memory resources when the create_csd() function returns an error, allowing a local privileged attacker to cause a denial of service through resource exhaustion. The vulnerability affects multiple Linux kernel versions across stable branches and has an EPSS score of 0.01% (percentile 2%), indicating low real-world exploitation probability despite the moderate CVSS 5.5 score. Patches are available from the Linux kernel maintainers across multiple stable branches.
A null pointer dereference vulnerability exists in the Linux kernel's MediaTek IOMMU driver where the platform_get_resource() function may return a NULL pointer without proper validation, leading to a crash when resource_size() attempts to dereference it. This affects all versions of the Linux kernel with the vulnerable MediaTek IOMMU code. A local attacker with low privileges can trigger a denial of service by causing a kernel panic, though the vulnerability is unlikely to be actively exploited in the wild given the low EPSS score of 0.01%.
A memory leak vulnerability exists in the Linux kernel's Rockchip clock driver (rockchip_clk_register_pll function) where allocated memory from kmemdup() is not freed when clk_register() fails, potentially causing denial of service through memory exhaustion. All versions of the Linux kernel with Rockchip clock support are affected. An attacker with local privileges can trigger repeated clock registration failures to exhaust system memory and crash the system, with an EPSS score of 0.01% indicating very low real-world exploitation probability despite the moderate CVSS score of 5.5.
A memory leak vulnerability exists in the Linux kernel's mxm-wmi (MXM WMI) platform driver where the ACPI buffer returned by wmi_evaluate_method() is not properly freed after invocation, leading to kernel memory exhaustion and potential denial of service. The vulnerability affects all versions of the Linux kernel with the mxm-wmi driver enabled, particularly systems with NVIDIA/AMD discrete GPU switching support. A local attacker with standard user privileges can repeatedly trigger the affected code path to exhaust kernel memory and crash the system, though the extremely low EPSS score (0.01th percentile) suggests exploitation is not actively observed in the wild.
This is a reference counting memory leak in the Linux kernel's radeon graphics driver, specifically in the radeon_atrm_get_bios() function where a PCI device pointer obtained via pci_get_class() is not properly released when loop conditions cause early exit. An authenticated local attacker with low privileges can trigger this vulnerability to cause a denial of service through kernel memory exhaustion, as unreleased PCI device objects accumulate in kernel memory. While no public exploit code exists (EPSS 0.01% indicates minimal real-world exploitation probability), the vulnerability affects all Linux kernel versions running the radeon driver and patches are available across multiple stable kernel series.
This vulnerability in the Linux kernel's NILFS2 filesystem causes a kernel panic when the system is booted with panic_on_warn enabled and checkpoint metadata corruption is detected. A local attacker with standard user privileges can trigger this denial of service by crafting malicious NILFS2 filesystem images or corrupting checkpoint metadata on disk, causing the kernel to panic and crash the system. The vulnerability affects multiple Linux kernel versions across several stable branches, with patches available from the vendor, but EPSS exploitation probability remains very low at 0.01 percentile, indicating this is not actively exploited in the wild.
A denial of service vulnerability (CVSS 5.5). Remediation should follow standard vulnerability management procedures. Vendor patch is available.
A memory leak vulnerability exists in the Linux kernel's AMD GPU (amdgpu) driver within the hpd_rx_irq_create_workqueue() function, where allocated memory for work queue structures fails to be properly freed if workqueue construction fails partway through initialization. This affects all Linux kernel versions with the vulnerable amdgpu driver code and requires local access with low privileges to trigger. An attacker can repeatedly trigger this condition to exhaust kernel memory and cause a denial of service, though the EPSS score of 0.01% indicates this is rarely exploited in practice. Patches are available from the Linux kernel stable branches.
A reference count leak exists in the Linux kernel's USB HID gadget driver (f_hid module) where the opts->refcnt is incremented but not properly decremented when report_desc allocation fails, leaving the options structure permanently locked and causing a denial of service condition. This affects all Linux kernel versions running the vulnerable USB gadget code path and requires local privilege to trigger. While the CVSS score is 5.5 (medium) and EPSS is extremely low at 0.01th percentile, patches are available from multiple stable kernel branches, indicating this is a real but low-priority issue with no known active exploitation.
A memory leak vulnerability exists in the Linux kernel's rtl8723bs WiFi driver initialization function rtw_init_cmd_priv(), where failure to allocate the response command buffer leaves the command buffer allocation unreleased. This affects all Linux kernel versions containing the vulnerable staging driver code and can be exploited by local attackers with low privileges to cause a denial of service through memory exhaustion. The vulnerability has a vendor-provided patch available across multiple stable kernel branches, and the EPSS score of 0.01% indicates minimal real-world exploitation probability despite the moderate CVSS 5.5 rating.
A memory leak vulnerability exists in the Linux kernel's ext4 fast commit (fc) implementation within the ext4_fc_record_regions() function. The vulnerability occurs when krealloc() fails and returns NULL, causing the function to improperly handle the state->fc_regions pointer, leaving allocated memory unreferenced and unable to be freed. This affects all Linux kernel versions with the vulnerable code path, allowing local attackers with unprivileged user access to exhaust kernel memory and trigger denial of service conditions. While the EPSS score of 0.01% indicates low real-world exploitation probability and no active exploitation is tracked in KEV data, the availability impact is high (CVSS score 5.5), and patches have been made available across multiple stable kernel branches.
This vulnerability is an undefined behavior issue in the Linux kernel's font handling code where a signed 32-bit left shift by 31 bits violates C language semantics, detected by UBSAN (Undefined Behavior Sanitizer). The vulnerability affects multiple Linux kernel versions starting from 2.6.23 and can be triggered by local users with low privileges during framebuffer console initialization, leading to denial of service through undefined behavior exploitation. While the EPSS score is extremely low at 0.01% (percentile 3%), patches are available from the kernel vendor and the issue has been resolved in stable releases.
A resource cleanup vulnerability exists in the Linux kernel's ARM SMMUv3 Performance Monitoring Unit (PMU) initialization code where a CPU hotplug callback registered via cpuhp_setup_state_multi() is not properly removed if platform_driver_register() fails, leading to a use-after-free condition. This affects Linux kernel versions across multiple stable branches and can be exploited by local attackers with limited privileges to trigger a denial of service through kernel panic or memory corruption. The vulnerability has a patch available from multiple kernel branches, with an EPSS score of 0.01% indicating low real-world exploitation probability despite the moderate CVSS 5.5 score.
A null pointer dereference vulnerability exists in the Linux kernel's Coda media driver due to missing validation of kmalloc return values. An unprivileged local attacker can trigger a denial of service condition by causing the kernel to dereference a null pointer, resulting in a system crash or hang. The vulnerability affects multiple Linux kernel versions across stable branches, though exploitation likelihood is low (EPSS 0.01%) and patches are readily available from vendors.

In the Linux kernel, the following vulnerability has been resolved: media: dvb-core: Fix double free in dvb_register_device() In function dvb_register_device() -> dvb_register_media_device() -> dvb_create_media_entity(), dvb->entity is allocated and initialized. If the initialization fails, it frees the dvb->entity, and return an error code. The caller takes the error code and handles the error by calling dvb_media_device_free(), which unregisters the entity and frees the field again if it is not NULL. As dvb->entity may not NULLed in dvb_create_media_entity() when the allocation of dvbdev->pad fails, a double free may occur. This may also cause an Use After free in media_device_unregister_entity(). Fix this by storing NULL to dvb->entity when it is freed.
CVE-2022-50498 is a security vulnerability (CVSS 5.5). Remediation should follow standard vulnerability management procedures. Vendor patch is available.
In the Linux kernel, the following vulnerability has been resolved: binfmt_misc: fix shift-out-of-bounds in check_special_flags UBSAN reported a shift-out-of-bounds warning: left shift of 1 by 31 places cannot be represented in type 'int' Call Trace: <TASK> __dump_stack lib/dump_stack.c:88 [inline] dump_stack_lvl+0x8d/0xcf lib/dump_stack.c:106 ubsan_epilogue+0xa/0x44 lib/ubsan.c:151 __ubsan_handle_shift_out_of_bounds+0x1e7/0x208 lib/ubsan.c:322 check_special_flags fs/binfmt_misc.c:241 [inline] create_entry fs/binfmt_misc.c:456 [inline] bm_register_write+0x9d3/0xa20 fs/binfmt_misc.c:654 vfs_write+0x11e/0x580 fs/read_write.c:582 ksys_write+0xcf/0x120 fs/read_write.c:637 do_syscall_x64 arch/x86/entry/common.c:50 [inline] do_syscall_64+0x34/0x80 arch/x86/entry/common.c:80 entry_SYSCALL_64_after_hwframe+0x63/0xcd RIP: 0033:0x4194e1 Since the type of Node's flags is unsigned long, we should define these macros with same type too.
Local privilege escalation and memory corruption in the Linux kernel process-creation path arises because copy_process() takes the wrong error-exit label after futex_hash_allocate_default() fails, releasing tasklist_lock and siglock that were never acquired. This lock imbalance can corrupt kernel synchronization state on the fork error path, with a potential for kernel crash or exploitation to gain elevated privileges. No public exploit identified at time of analysis and EPSS is low (0.17%), consistent with a subtle, hard-to-trigger error-handling defect rather than a widely-weaponized bug.
Out-of-bounds memory access in the Linux kernel's in-kernel SMB/CIFS client (smb2_compound_op() in fs/smb/client) stems from wrong index references when iterating over compound SMB2 response buffers; a computed index at or above MAX_COMPOUND drives reads/writes past the response array. A machine mounting a share from a malicious or compromised SMB server can have its kernel process attacker-influenced compound responses, leading to memory corruption, denial of service, or potential privilege escalation. It carries a CNA-assigned CVSS 9.8, but there is no public exploit identified at time of analysis and EPSS is very low (0.19%, 8th percentile), so real-world exploitation pressure is currently minimal.
Privilege escalation and host memory corruption in the Linux kernel's i40e Intel Ethernet driver allows a malicious or buggy SR-IOV virtual function to send a crafted 'config queues' mailbox message with an out-of-range channel index, causing out-of-bounds access to the vf->ch[idx] array in i40e_vc_config_queues_msg(). Exploitation crosses the VF-to-host trust boundary (CVSS scope change) and can disclose or corrupt host kernel memory. The issue is fixed upstream across multiple stable trees; no public exploit and no CISA KEV listing exist, and EPSS is low (0.20%, 10th percentile), indicating no public exploit identified at time of analysis.
Local privilege escalation and memory corruption in the Linux kernel's fbcon (framebuffer console) subsystem stems from integer overflows in fbcon_do_set_font() when computing font buffer sizes from user-controlled parameters. A local, low-privileged attacker who can invoke the font-setting ioctl can trigger undersized allocations followed by heap buffer overflows during font data copying, potentially achieving code execution in kernel context. EPSS is low (0.16%, 6th percentile) and there is no public exploit identified at time of analysis; the fix has been merged and backported across stable kernel trees.
Local privilege escalation via memory corruption in the Linux kernel's iommufd subsystem allows a low-privileged local user to trigger a use-after-free by racing the abort path of IOMMU object allocation. Because fput() defers file release to a workqueue while the code immediately kfree()s the tied iommufd_object, the deferred release() decrements a users refcount on already-freed memory, corrupting the slab. Only pre-release 6.17-rc kernels are affected; EPSS is 0.10% (1st percentile) and there is no public exploit identified at time of analysis.
Out-of-memory denial of service affects applications that use the Go library github.com/nwaples/rardecode 2.1.1 and earlier to unpack RAR archives: a crafted archive can declare an oversized dictionary (window) size that the decoder allocates without enforcing a per-call bound, exhausting memory and crashing the process. Exploitation requires the target application to open the attacker-supplied archive (CVSS UI:R); no credentials are needed on the attacker side (PR:N), and the impact is availability-only (C:N/I:N/A:H, CVSS 6.5). Risk is genuine but moderate: EPSS is 0.37% (29th percentile), there is no CISA KEV entry, and no public exploit code has been identified at time of analysis - deployments that never ingest externally controlled RAR files are effectively unaffected.
Kernel-level memory corruption in the Linux kernel's rxrpc/RxGK subsystem allows an out-of-bounds access when the rxgk_yfs_decode_ticket() function parses an authentication response packet. The flaw stems from an unchecked unsigned subtraction ('ticket_len - 10 * 4') on attacker-influenced length data, which can underflow and drive an out-of-bounds write (CWE-787). It affects Linux 6.17 release-candidate kernels (rc1 through rc6); there is no public exploit identified at time of analysis, and EPSS exploitation probability is very low at 0.13% (3rd percentile).
Local privilege escalation and kernel memory disclosure in the Linux kernel's GPIO ACPI subsystem (gpiolib) affects development builds 6.17-rc1 through 6.17-rc6, where an uninitialized acpi_gpio_info structure is passed to __acpi_find_gpio() and its stale info->quirks field is later consumed in acpi_populate_gpio_lookup(). The regression, introduced by commit 7c010d463372, breaks the i2c_hid_acpi driver (probe fails with -EINVAL / 'has not been provided an Int IRQ') and causes the kernel to act on uninitialized stack memory. No public exploit identified at time of analysis, and EPSS is low at 0.14% (4th percentile), consistent with a hard-to-weaponize local memory-safety regression confined to release candidates.
Improper authorization in Casdoor (an open-source Identity and Access Management / SSO platform) versions 2.26.0 and earlier lets a remote authenticated administrator of ANY organization escalate beyond their tenant boundary. Because the permission-verification module and the organization/application editing interface fail to enforce object-level scope, a low-trust org admin can bypass access controls simply by concatenating/manipulating URLs after login to read and modify resources belonging to other organizations. A public technical writeup/PoC gist exists; it is not listed in CISA KEV and EPSS is low (0.61%, 45th percentile), so exploitation is plausible but not confirmed in the wild. Fixed in v2.63.0.
In the Linux kernel, the following vulnerability has been resolved: blk-mq: use quiesced elevator switch when reinitializing queues The hctx's run_work may be racing with the elevator switch when. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. This Use After Free vulnerability could allow attackers to access freed memory to execute arbitrary code or crash the application.
A logic error in the Linux kernel's device mapper thin pool module causes infinite loops and system hangs when metadata commits fail. The vulnerability affects Linux kernel systems with dm-thin storage pools; when a commit fails during btree metadata operations, the pmd->root pointer is not properly restored to the last valid transaction state, causing subsequent read operations to traverse a corrupted btree structure. An unprivileged local attacker with access to the system can trigger this denial of service condition, resulting in kernel softlockups and system hangs. While no public exploit code is widely distributed, the vulnerability is straightforward to trigger through storage I/O operations on affected systems.
A null pointer dereference vulnerability exists in the Linux kernel's WiFi mac80211 MLME (MAC Layer Management Entity) implementation that crashes the kernel during WiFi association tracing when an AP connection without link 0 fails. The vulnerability affects all Linux kernel versions with the vulnerable code path in the mac80211 wireless driver subsystem, allowing a local authenticated attacker to trigger a denial of service condition. The EPSS score of 0.01% indicates this is rarely exploited in practice, though patches are publicly available from kernel.org.
A resource leak vulnerability exists in the Linux kernel's mpt3sas SCSI transport driver where the sas_rphy_add() function can fail without properly freeing allocated resources, leading to a NULL pointer dereference and kernel crash during device removal. This affects Linux kernel implementations across multiple versions that use the mpt3sas driver for SAS (Serial Attached SCSI) HBA management. An unprivileged local attacker with sufficient privileges to trigger transport port operations can cause a denial of service by inducing a kernel panic, though the low EPSS score of 0.01% suggests exploitation is not practically demonstrated in the wild.
An information leak vulnerability exists in the Linux kernel's TIPC (Transparent Inter-Process Communication) subsystem within the tipc_topsrv_kern_subscr() function. The vulnerability occurs due to incomplete initialization of the sub.usr_handle field, leaving four bytes uninitialized when setsockopt() is called with SOL_TIPC options, allowing kernel memory contents to be leaked to user space. This affects Linux kernel versions including 6.1-rc1 and potentially others; while the EPSS score is extremely low at 0.01% percentile, the vulnerability requires local access and low privileges to trigger, making it a lower-priority but real information disclosure issue that has been patched by multiple vendors.
A null pointer dereference vulnerability exists in the Linux kernel's block layer (blk-mq) memory allocation path that can be triggered by a local, low-privileged user to cause a denial of service. The vulnerability affects Linux kernel versions including 6.1-rc1 and potentially other versions where a failed memory allocation during block queue tag initialization leaves a dangling pointer that is later dereferenced during cleanup. While the EPSS score is low (0.02%, percentile 4%), the vulnerability is straightforward to trigger under memory pressure conditions, requires only local access with minimal privileges, and has vendor patches available.
A memory leak vulnerability exists in the Linux kernel's test_firmware module initialization function (test_firmware_init) where allocated memory for test_fw_config->name is not properly freed when misc_register() fails. This affects all versions of the Linux kernel with the test_firmware module compiled, allowing local authenticated attackers to exhaust kernel memory and cause a denial of service. The vulnerability has a patch available from the Linux kernel maintainers, with an EPSS score of 0.01% indicating very low real-world exploitation probability despite the moderate CVSS score.
A memory corruption vulnerability exists in the Linux kernel's MSM display port driver that occurs when more than eight display bridges are connected, allowing local attackers with low privileges to corrupt kernel memory beyond a fixed-size array. The vulnerability affects Linux kernel versions up to 6.1-rc2 and requires local access to exploit, with no known active exploitation in the wild (not in KEV) and a very low EPSS score of 0.02% indicating minimal real-world exploitation likelihood.
A resource leak vulnerability exists in the Linux kernel's FSL PAMU (Freescale Peripheral Access Management Unit) IOMMU driver where the fsl_pamu_probe() function fails to release IRQ and memory resources when the create_csd() function returns an error, allowing a local privileged attacker to cause a denial of service through resource exhaustion. The vulnerability affects multiple Linux kernel versions across stable branches and has an EPSS score of 0.01% (percentile 2%), indicating low real-world exploitation probability despite the moderate CVSS 5.5 score. Patches are available from the Linux kernel maintainers across multiple stable branches.
A null pointer dereference vulnerability exists in the Linux kernel's MediaTek IOMMU driver where the platform_get_resource() function may return a NULL pointer without proper validation, leading to a crash when resource_size() attempts to dereference it. This affects all versions of the Linux kernel with the vulnerable MediaTek IOMMU code. A local attacker with low privileges can trigger a denial of service by causing a kernel panic, though the vulnerability is unlikely to be actively exploited in the wild given the low EPSS score of 0.01%.
A memory leak vulnerability exists in the Linux kernel's Rockchip clock driver (rockchip_clk_register_pll function) where allocated memory from kmemdup() is not freed when clk_register() fails, potentially causing denial of service through memory exhaustion. All versions of the Linux kernel with Rockchip clock support are affected. An attacker with local privileges can trigger repeated clock registration failures to exhaust system memory and crash the system, with an EPSS score of 0.01% indicating very low real-world exploitation probability despite the moderate CVSS score of 5.5.
A memory leak vulnerability exists in the Linux kernel's mxm-wmi (MXM WMI) platform driver where the ACPI buffer returned by wmi_evaluate_method() is not properly freed after invocation, leading to kernel memory exhaustion and potential denial of service. The vulnerability affects all versions of the Linux kernel with the mxm-wmi driver enabled, particularly systems with NVIDIA/AMD discrete GPU switching support. A local attacker with standard user privileges can repeatedly trigger the affected code path to exhaust kernel memory and crash the system, though the extremely low EPSS score (0.01th percentile) suggests exploitation is not actively observed in the wild.
This is a reference counting memory leak in the Linux kernel's radeon graphics driver, specifically in the radeon_atrm_get_bios() function where a PCI device pointer obtained via pci_get_class() is not properly released when loop conditions cause early exit. An authenticated local attacker with low privileges can trigger this vulnerability to cause a denial of service through kernel memory exhaustion, as unreleased PCI device objects accumulate in kernel memory. While no public exploit code exists (EPSS 0.01% indicates minimal real-world exploitation probability), the vulnerability affects all Linux kernel versions running the radeon driver and patches are available across multiple stable kernel series.
This vulnerability in the Linux kernel's NILFS2 filesystem causes a kernel panic when the system is booted with panic_on_warn enabled and checkpoint metadata corruption is detected. A local attacker with standard user privileges can trigger this denial of service by crafting malicious NILFS2 filesystem images or corrupting checkpoint metadata on disk, causing the kernel to panic and crash the system. The vulnerability affects multiple Linux kernel versions across several stable branches, with patches available from the vendor, but EPSS exploitation probability remains very low at 0.01 percentile, indicating this is not actively exploited in the wild.
A denial of service vulnerability (CVSS 5.5). Remediation should follow standard vulnerability management procedures. Vendor patch is available.
A memory leak vulnerability exists in the Linux kernel's AMD GPU (amdgpu) driver within the hpd_rx_irq_create_workqueue() function, where allocated memory for work queue structures fails to be properly freed if workqueue construction fails partway through initialization. This affects all Linux kernel versions with the vulnerable amdgpu driver code and requires local access with low privileges to trigger. An attacker can repeatedly trigger this condition to exhaust kernel memory and cause a denial of service, though the EPSS score of 0.01% indicates this is rarely exploited in practice. Patches are available from the Linux kernel stable branches.
A reference count leak exists in the Linux kernel's USB HID gadget driver (f_hid module) where the opts->refcnt is incremented but not properly decremented when report_desc allocation fails, leaving the options structure permanently locked and causing a denial of service condition. This affects all Linux kernel versions running the vulnerable USB gadget code path and requires local privilege to trigger. While the CVSS score is 5.5 (medium) and EPSS is extremely low at 0.01th percentile, patches are available from multiple stable kernel branches, indicating this is a real but low-priority issue with no known active exploitation.
A memory leak vulnerability exists in the Linux kernel's rtl8723bs WiFi driver initialization function rtw_init_cmd_priv(), where failure to allocate the response command buffer leaves the command buffer allocation unreleased. This affects all Linux kernel versions containing the vulnerable staging driver code and can be exploited by local attackers with low privileges to cause a denial of service through memory exhaustion. The vulnerability has a vendor-provided patch available across multiple stable kernel branches, and the EPSS score of 0.01% indicates minimal real-world exploitation probability despite the moderate CVSS 5.5 rating.
A memory leak vulnerability exists in the Linux kernel's ext4 fast commit (fc) implementation within the ext4_fc_record_regions() function. The vulnerability occurs when krealloc() fails and returns NULL, causing the function to improperly handle the state->fc_regions pointer, leaving allocated memory unreferenced and unable to be freed. This affects all Linux kernel versions with the vulnerable code path, allowing local attackers with unprivileged user access to exhaust kernel memory and trigger denial of service conditions. While the EPSS score of 0.01% indicates low real-world exploitation probability and no active exploitation is tracked in KEV data, the availability impact is high (CVSS score 5.5), and patches have been made available across multiple stable kernel branches.
This vulnerability is an undefined behavior issue in the Linux kernel's font handling code where a signed 32-bit left shift by 31 bits violates C language semantics, detected by UBSAN (Undefined Behavior Sanitizer). The vulnerability affects multiple Linux kernel versions starting from 2.6.23 and can be triggered by local users with low privileges during framebuffer console initialization, leading to denial of service through undefined behavior exploitation. While the EPSS score is extremely low at 0.01% (percentile 3%), patches are available from the kernel vendor and the issue has been resolved in stable releases.
A resource cleanup vulnerability exists in the Linux kernel's ARM SMMUv3 Performance Monitoring Unit (PMU) initialization code where a CPU hotplug callback registered via cpuhp_setup_state_multi() is not properly removed if platform_driver_register() fails, leading to a use-after-free condition. This affects Linux kernel versions across multiple stable branches and can be exploited by local attackers with limited privileges to trigger a denial of service through kernel panic or memory corruption. The vulnerability has a patch available from multiple kernel branches, with an EPSS score of 0.01% indicating low real-world exploitation probability despite the moderate CVSS 5.5 score.
A null pointer dereference vulnerability exists in the Linux kernel's Coda media driver due to missing validation of kmalloc return values. An unprivileged local attacker can trigger a denial of service condition by causing the kernel to dereference a null pointer, resulting in a system crash or hang. The vulnerability affects multiple Linux kernel versions across stable branches, though exploitation likelihood is low (EPSS 0.01%) and patches are readily available from vendors.

If the initialization fails, it frees the dvb->entity, and return an error code. The caller takes the error code and handles the error by calling dvb_media_device_free(), which unregisters the entity and frees the field again if it is not NULL. As dvb->entity may not NULLed in dvb_create_media_entity() when the allocation of dvbdev->pad fails, a double free may occur. This may also cause an Use After free in media_device_unregister_entity(). Fix this by storing NULL to dvb->entity when it is freed.
CVE-2022-50498 is a security vulnerability (CVSS 5.5). Remediation should follow standard vulnerability management procedures. Vendor patch is available.
