Description Pedro Sampaio 2020-11-13 17:57:19 UTC 
A flaw was found in the Linux kernels implementation of extended attributes while working on a journaled filesystem.  

An attacker with local access with permissions to modify extended attributes on a local filesystem can possibly crash the system.
