CVE-2022-50022 Information

Jun 19, 2025 cve

Description

In the Linux kernel the following vulnerability has been resolved:

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

In line 2884 aid5_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 aid5_release_stripe(sh);\ to the bottom of the function.
