Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ubifswbufwritenolock: A read out-of-bounds issue exists in this function. This issue occurs when ubifswbufwritenolock attempts to access memory beyond the allocated bounds of the buffer buf. Here’s an example of how this issue...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: “hungtask”: fixed warnings caused by unaligned lock pointers. The blocker tracking mechanism assumes that lock pointers are at least 4-byte aligned so that their lower bits can be used for type encoding. However, as reported by...

CVE-2025-68250

The CVE-2025-68250 entry is about a Linux kernel issue where the blocker tracking mechanism assumed 4-byte alignment for lock pointers to encode types in lower bits. On architectures like m68k with only 2-byte alignment for 32-bit values, two WARN_ON_ONCE checks could trigger. The fix silently ig...
