kernel: xfrm: defensively unhash xfrm_state lists in __xfrm_state_delete

A flaw was found in the Linux kernel's xfrm IPSec framework subsystem. This vulnerability, a use-after-free, occurs when the system incorrectly manages memory related to security policies, specifically during the deletion of xfrmstate lists. An attacker with local access could exploit this flaw b...

CVE-2026-74630

A flaw was found in the Linux kernel's IPv6 subsystem. The in6devget function can incorrectly increment the reference count of an inet6dev object after it has been freed, leading to a use-after-free vulnerability. A local attacker could exploit this to cause memory corruption, potentially resulti...

CVE-2026-74637

A flaw was found in the Linux kernel's perf subsystem. A local attacker could exploit a use-after-free vulnerability when a perf event group's sibling is detached but remains active, and its pointer to the group leader is not properly updated. This improper handling can lead to a system crash,...

CVE-2026-74636

A flaw was found in the Linux kernel. A race condition exists between the updateeventfields and eventdefinefields functions within the tracing subsystem. A local user, by loading specific modules, could exploit this unprotected access to kernel fields. This could lead to a kernel panic, resulting...

CVE-2026-74658

A flaw was found in the Linux kernel's futex subsystem. A race condition during robust futex unlock operations can occur when a process waiting on a futex is killed before it can acquire the futex, and another process subsequently re-acquires the futex through a fast path. This can lead to a...

CVE-2026-74681

A flaw was found in the Linux kernel's USB subsystem, specifically within the usbio module. An incorrect buffer size validation occurs in the usbiobulkmsg function, where the bulk IN receive buffer size is mistakenly compared against the bulk OUT endpoint size instead of the actual receive buffer...

CVE-2026-74635

A flaw was found in the Linux kernel's fbdev subsystem, specifically within the bitcursor function. A local user can exploit this vulnerability by writing arbitrary values to the /dev/vcsa device or by manipulating font changes. This improper handling of glyph indices can lead to an out-of-bounds...

CVE-2026-74596

A flaw was found in the Linux kernel's fsverity subsystem. The vulnerability is due to the removal of a check in the setattrprepare function, which previously verified if fs-verity was enabled. This change allows fsverity files to be truncated even when the fs-verity feature is not active on the...

CVE-2026-74594

A flaw was found in the Linux kernel's Pressure Stall Information PSI subsystem. A race condition exists where a timer rtpolltimer can be re-armed after it has been deleted during the destruction of a control group cgroup. This can lead to the timer function executing on freed memory, potentially...

CVE-2026-74685

A flaw was found in the Linux kernel's hwmon subsystem, specifically within the ltc4282 driver. When a negative value is passed to the ltc4282writecurr function, an incorrect type cast converts this input into a large positive value. This leads to an integer overflow, causing the current limit to...

CVE-2026-74711

A flaw was found in the Linux kernel's hardware monitoring hwmon subsystem, specifically within the Power Management Bus pmbus driver. This vulnerability arises from a type confusion issue where the system incorrectly interprets data types during notification processing. An attacker could exploit...

CVE-2026-74671

A flaw was found in the Linux kernel's Integrity Measurement Architecture IMA subsystem. The xattrverify function, which verifies extended attributes, incorrectly mixes int and sizet data types in its digest-length check. This can lead to an integer underflow when processing a truncated extended...

CVE-2026-74646

A flaw was found in the Linux kernel's fastrpc subsystem. When an invoke operation is interrupted by a signal, the fastrpcinternalinvoke function moves memory mappings without properly holding the fl-lock. This missing lock during memory map manipulation creates a race condition, which could lead...

CVE-2026-74675

A flaw was found in the Linux kernel. A race condition exists in the kbdkeycode function within the virtual terminal vt subsystem. This occurs when kbdkeycode attempts to read a terminal tty reference without properly acquiring and holding it, while the conshutdown function can concurrently clear...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ASoC: soc-pcm: Added a NULL check in BE reparenting. A NULL check was also added to the dpcmbereparent API, to handle kernel NULL pointer dereferencing errors. This issue occurred during fuzzing tests...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ALSA: usx2y – Do not call freepagesexact with a NULL address. Unlike some other functions, we cannot pass a NULL pointer to freepagesexact. Add a proper NULL check to avoid potential errors...
