CVE-2026-53105

A flaw was found in the Linux kernel's Wi-Fi subsystem, specifically within the mt76: mt7925 driver. This vulnerability occurs due to a missing check for a NULL 'vif' Virtual Interface before it is accessed. An attacker could potentially trigger a kernel panic by exploiting scenarios where the...

EUVD-2026-39304

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: fix krealloc memory leak Don't just overwrite the original pointer passed to krealloc with its return value without checking latter: MEM = kreallocMEM, SZ, GFP; If krealloc returns NULL, that erases the pointer to the...

CVE-2026-53213

CVE-2026-53213 affects the Linux kernel’s DRM VC4 path. The vulnerability is a memory-leak scenario in krealloc(): if krealloc() returns NULL, the original pointer may be overwritten, leaking the previously allocated memory. The advised fix uses a temporary variable to hold krealloc()’s return va...

CVE-2026-53158

The CVE-2026-53158 issue affects the Linux kernel’s fastrpc rpmsg path. A NULL pointer dereference could occur at boot when a DSP glink message arrives before fastrpc_rpmsg_probe() has finished initialization, causing a crash from an uninitialized spinlock on the fastrpc_channel_ctx. The root cau...

PT-2026-51731

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A NULL pointer dereference exists in the BPF Berkeley Packet Filter subsystem. The function bpf selem unlink nofail sets the smap variable to NULL before removing the element from the...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: cppccpufreq: Fixed a possible null pointer dereferencing issue. The functions cppccpufreqgetrate and hiicppccpufreqgetrate can be called from different locations with various parameters. Therefore, cpufreqcpuget may return null a...

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...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: virtionet: a memory leak inside XPDTX has been fixed using mergeable. When we call xdpconvertbufftoframe to obtain xdpf, if it returns NULL, we should check whether xdppage was allocated by xdplinearizepage. If it was newly...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: PM: hibernate: Fixed a crash that occurred when freeing an invalid crypto compressor. When cryptoallocacomp fails, it returns an ERRPTR value instead of NULL. The cleanup code in savecompressedimage and loadcompressedimage...
