CVE-2022-50022

HighCVSS 7.8/10Last modified Aug 4, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

drivers:md:fix a potential use-after-free bug

In line 2884, "raid5_release_stripe(sh);" drops the reference to sh and may cause sh to be released. However, sh is subsequently used in lines 2886 "if (sh->batch_head && sh != sh->batch_head)". This may result in an use-after-free bug.

It can be fixed by moving "raid5_release_stripe(sh);" to the bottom of the function.
