Memory ordering race condition in the Linux kernel's blk-cgroup I/O accounting subsystem allows a local low-privileged user to corrupt kernel linked-list structures, potentially causing a system crash or kernel memory corruption. The flaw arises when CPU instruction reordering causes `__blkcg_rstat_flush()` to read a stale or partially-initialized `next_bisc` pointer while `blk_cgroup_bio_start()` concurrently modifies the statistics list, resolved only by inserting a memory barrier. With a CVSS 7.8 score (AV:L/AC:L/PR:L) but a low EPSS of 0.24% at the 15th percentile, this is a genuine kernel integrity issue with no confirmed active exploitation and no known public proof-of-concept at time of analysis.

Filesystem metadata corruption in the Linux kernel's f2fs compress subsystem stems from a missing cp_rwsem lock around the reserve_compress_blocks() and release_compress_blocks() functions, creating a race condition with checkpoint operations. Systems using f2fs with compression enabled are at risk of corrupted block addresses in dnode structures, inode fields, and the global total_valid_block_count counter if a Sudden Power Off (SPO) occurs during the race window. No public exploit exists and EPSS is 0.02% (6th percentile), marking this as a data integrity and reliability concern rather than an active attack target.

Use-after-free via race condition in the Linux kernel's USB gadget audio driver (u_audio) allows a local low-privileged user to corrupt kernel memory during gadget unbind operations. The flaw exists because audio control pointers were accessed concurrently without adequate locking after the underlying memory was freed during device unbind, a classic CWE-362 time-of-check/time-of-use pattern. EPSS is low (0.17%, 7th percentile) and CISA KEV does not list this CVE, but the CVSS C:H/I:H/A:H rating reflects potential for local privilege escalation via memory corruption.

Buffer overflow in the Linux kernel's NTFS3 filesystem driver (`ntfs_set_label()`) allows a local attacker with low privileges to corrupt memory by triggering a memcpy of up to 256 bytes into a fixed 20-byte buffer (`uni->name`). The root cause is a fixed-size array declaration that does not accommodate the maximum Unicode volume-label length, identified via smatch static analysis. No public exploit code or confirmed active exploitation (CISA KEV) has been identified at time of analysis; however, the CVSS 7.8 rating reflects the potential for high-impact local exploitation with full confidentiality, integrity, and availability consequences.

This NULL Pointer Dereference vulnerability could allow attackers to crash the application by dereferencing a null pointer.
Stale pointer dereference in the Linux kernel's ALSA HDA Cirrus Logic DSP (CS DSP) audio driver allows a local low-privileged attacker to trigger kernel memory corruption by accessing orphaned ALSA sound controls after the amp driver is unloaded. The flaw originates in hda_cs_dsp_control_remove() failing to call snd_ctl_remove(), leaving ALSA controls registered with the soundcard while their backing memory is freed - exposing a dangling private_data pointer accessible via standard ALSA interfaces. No public exploit code has been identified and EPSS scores this at 0.22% (12th percentile), though the CVSS 7.8 score accurately reflects the potential for full kernel compromise if exploitation succeeds on hardware-eligible systems.

This Out-of-bounds Read vulnerability could allow attackers to read data from memory outside the intended buffer boundaries.
NULL module pointer assignment in the Linux kernel ALSA sound core creates a reference-counting gap that enables a race condition between device open/close operations and module unloading. When the ALSA sound core is built into the kernel (CONFIG_SND=y) but a sound driver such as CONFIG_SND_USB_AUDIO is compiled as a loadable module, a misplaced #ifdef MODULE guard causes card->module to remain NULL, bypassing module reference tracking entirely. A local attacker with low privileges can exploit the resulting race - opening a sound device then triggering or racing a module unload - to potentially cause a kernel crash (DoS) or, in the best-case scenario for an attacker, achieve arbitrary code execution in kernel context. No public exploit identified at time of analysis; EPSS of 1.09% (61st percentile) reflects moderate research interest with low absolute exploitation probability, and the vulnerability is not listed in CISA KEV.

Memory ordering race condition in the Linux kernel's blk-cgroup I/O accounting subsystem allows a local low-privileged user to corrupt kernel linked-list structures, potentially causing a system crash or kernel memory corruption. The flaw arises when CPU instruction reordering causes `__blkcg_rstat_flush()` to read a stale or partially-initialized `next_bisc` pointer while `blk_cgroup_bio_start()` concurrently modifies the statistics list, resolved only by inserting a memory barrier. With a CVSS 7.8 score (AV:L/AC:L/PR:L) but a low EPSS of 0.24% at the 15th percentile, this is a genuine kernel integrity issue with no confirmed active exploitation and no known public proof-of-concept at time of analysis.

Filesystem metadata corruption in the Linux kernel's f2fs compress subsystem stems from a missing cp_rwsem lock around the reserve_compress_blocks() and release_compress_blocks() functions, creating a race condition with checkpoint operations. Systems using f2fs with compression enabled are at risk of corrupted block addresses in dnode structures, inode fields, and the global total_valid_block_count counter if a Sudden Power Off (SPO) occurs during the race window. No public exploit exists and EPSS is 0.02% (6th percentile), marking this as a data integrity and reliability concern rather than an active attack target.

Use-after-free via race condition in the Linux kernel's USB gadget audio driver (u_audio) allows a local low-privileged user to corrupt kernel memory during gadget unbind operations. The flaw exists because audio control pointers were accessed concurrently without adequate locking after the underlying memory was freed during device unbind, a classic CWE-362 time-of-check/time-of-use pattern. EPSS is low (0.17%, 7th percentile) and CISA KEV does not list this CVE, but the CVSS C:H/I:H/A:H rating reflects potential for local privilege escalation via memory corruption.

Buffer overflow in the Linux kernel's NTFS3 filesystem driver (`ntfs_set_label()`) allows a local attacker with low privileges to corrupt memory by triggering a memcpy of up to 256 bytes into a fixed 20-byte buffer (`uni->name`). The root cause is a fixed-size array declaration that does not accommodate the maximum Unicode volume-label length, identified via smatch static analysis. No public exploit code or confirmed active exploitation (CISA KEV) has been identified at time of analysis; however, the CVSS 7.8 rating reflects the potential for high-impact local exploitation with full confidentiality, integrity, and availability consequences.

Stale pointer dereference in the Linux kernel's ALSA HDA Cirrus Logic DSP (CS DSP) audio driver allows a local low-privileged attacker to trigger kernel memory corruption by accessing orphaned ALSA sound controls after the amp driver is unloaded. The flaw originates in hda_cs_dsp_control_remove() failing to call snd_ctl_remove(), leaving ALSA controls registered with the soundcard while their backing memory is freed - exposing a dangling private_data pointer accessible via standard ALSA interfaces. No public exploit code has been identified and EPSS scores this at 0.22% (12th percentile), though the CVSS 7.8 score accurately reflects the potential for full kernel compromise if exploitation succeeds on hardware-eligible systems.

NULL module pointer assignment in the Linux kernel ALSA sound core creates a reference-counting gap that enables a race condition between device open/close operations and module unloading. When the ALSA sound core is built into the kernel (CONFIG_SND=y) but a sound driver such as CONFIG_SND_USB_AUDIO is compiled as a loadable module, a misplaced #ifdef MODULE guard causes card->module to remain NULL, bypassing module reference tracking entirely. A local attacker with low privileges can exploit the resulting race - opening a sound device then triggering or racing a module unload - to potentially cause a kernel crash (DoS) or, in the best-case scenario for an attacker, achieve arbitrary code execution in kernel context. No public exploit identified at time of analysis; EPSS of 1.09% (61st percentile) reflects moderate research interest with low absolute exploitation probability, and the vulnerability is not listed in CISA KEV.
