Linux Kernel EROFS Compressed Extents Algorithm Validation Vulnerability

Vulnerability

A vulnerability in the Linux kernel's EROFS (Enhanced Read-Only File System) implementation has been addressed. The issue arose because the algorithm used to validate encoded extents did not properly accommodate new encoding methods. This vulnerability affects the Linux kernel stable tree.

Impact

The vulnerability could lead to file system corruption by allowing inconsistent or incorrect handling of compressed data, potentially causing data integrity issues when reading or writing files.
