Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 7.1. It stems from improper handling of FITRIM range alignment within ntfstrimfs. When the start of the free space is not aligned with the discard granularity, it may extend the discard range beyond allocated clusters, resulting in those...
