Vulnerability from github – Published: 2022-05-14 03:38 – Updated: 2025-04-12 13:05

Details

The mbcache feature in the ext2 and ext4 filesystem implementations in the Linux kernel before 4.6 mishandles xattr block caching, which allows local users to cause a denial of service (soft lockup) via filesystem operations in environments that use many attributes, as demonstrated by Ceph and Samba.

Severity ?

5.5 (Medium)
