SUSE CVE-2026-31561

In the Linux kernel, the following vulnerability has been resolved: x86/cpu: Remove X86CR4FRED from the CR4 pinned bits mask Commit in Fixes added the FRED CR4 bit to the CR4 pinned bits mask so that whenever something else modifies CR4, that bit remains set. Which in itself is a perfectly fine...

CVE-2026-31561

A flaw was found in the Linux kernel's handling of the CR4 pinned bits mask for FRED Flexible Return and Event Delivery. An attacker could exploit this by modifying a specific bit in memory to disable CR4 pinning, potentially leading to a system crash. This vulnerability could result in a Denial ...
