Linux Distros Unpatched Vulnerability : CVE-2026-23344

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - crypto: ccp - Fix use-after-free on error path In the error path of sevtsminitlocked, the code dereferences 't' after it has been freed with kfree. The prerr...

CVE-2026-23344

A flaw was found in the Linux kernel's crypto: ccp module. A use-after-free vulnerability exists in the sevtsminitlocked function's error handling path. This occurs when the system attempts to access memory that has already been released, leading to a memory corruption vulnerability. This could...
