Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ext4: a potential memory leak has been fixed in ext4fcrecordregions. Since krealloc may return NULL, in this case, state-fcregions may not be freed by krealloc. However, state-fcregions is already set to NULL. This could lead to ...

Use After Free

Overview Affected versions of this package are vulnerable to Use After Free in the CheckPrimitiveExtent function. An attacker can cause a crash by triggering a failed memory allocation, leading to use of freed memory. Remediation A fix was pushed into the master branch but not yet published...

In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: osdep: avoid NULL pointer dereference in rtwcbufalloc The return value of kzallocflex is used without ensuring that the allocation succeeded, and the pointer is dereferenced unconditionally. Guard the access t...

CVE-2026-47271

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.0, src/mem.c implemented out-of-memory guards for xmalloc, xrealloc, and xstrdup using assertdata != NULL. The C standard specifies that all assert expressions are compiled out when NDEBUG is defined at...

In the Linux kernel, the following vulnerability has been resolved: kunit: Executor: Fixed a memory leak in cases where kunitfiltertests fails. It is possible that memory allocation for the “filtered” data may fail, but the copy of the suite may still succeed. In such cases, the “copy” data might...

Astra Linux - уязвимость в glibc

The Name Service Cache Daemon’s nscd netgroup cache uses xmalloc or xrealloc, and these functions may terminate the process due to a memory allocation failure, resulting in a denial of service for clients. The flaw was introduced in glibc 2.15 when the cache was added to nscd. This vulnerability ...

CVE-2026-44638

A flaw was found in libsixel, a SIXEL encoder/decoder implementation. An incorrect NULL check after a memory allocation call in the sixeldecoderaw and sixeldecode functions can lead to a NULL pointer dereference. This occurs when memory allocation fails, causing the process to crash and resulting...

PT-2026-41034

libsixel is a SIXEL encoder/decoder implementation derived from kmiya's sixel. From to 1.8.7-r1, a wrong NULL check after an allocation call in sixel decode raw and sixel decode causes a NULL pointer dereference whenever the allocation fails. The check tests the address of the output parameter...
