Linux

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.
