USN-7940-1: Linux kernel (Azure FIPS) vulnerabilities

Jean-Claude Graf, Sandro Rüegge, Ali Hajiabadi, and Kaveh Razavi discovered that the Linux kernel contained insufficient branch predictor isolation between a guest and a userspace hypervisor for certain processors. This flaw is known as VMSCAPE. An attacker in a guest VM could possibly use this t...

CVE-2025-68262

The provided sources describe a Linux kernel vulnerability: a double-free in the crypto/zstd per-CPU streams when multiple tfms are freed, caused by freeing zstd_streams in zstd_exit() on every tfm destruction. The recommended fix is to change lifecycle management so the streams are freed only on...

CVE-2025-68262 crypto: zstd - fix double-free in per-CPU stream cleanup

In the Linux kernel, the following vulnerability has been resolved: crypto: zstd - fix double-free in per-CPU stream cleanup The crypto/zstd module has a double-free bug that occurs when multiple tfms are allocated and freed. The issue happens because zstdstreams per-CPU contexts are freed in...
