Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Fixed the jump offset calculation in tailcall. The additional call to bpfintjitcompile skips the JIT context initialization. This effectively skips the offset calculation, resulting in outoffset = -1. Therefore, t...

CVE-2026-80958

A flaw was found in the dm-pcache component of the Linux kernel. The tail-kset read operations, used by cachereplay, the writeback worker, and the garbage collection GC worker, incorrectly calculate the length of the data region. This error causes the system to read beyond the intended segment da...
