CVE-2022-49651 Information

Description

In the Linux kernel the following vulnerability has been resolved:

srcu: Tighten cleanup_srcu_struct() GP checks

Currently cleanup_srcu_struct() checks for a grace period in progress but it does not check for a grace period that has not yet started but which might start at any time. Such a situation could result in a use-after-free bug so this commit adds a check for a grace period that is needed but not yet started to cleanup_srcu_struct().
