Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.17.1

Description The issue is related to the jbd2 journal wait updates function in the Linux kernel, specifically in the fs/jbd2/transaction.c file. It involves a use-after-free condition caused by a transaction t race condition, which can be exploited by a remote attacker to execute arbitrary code.

Recommendations For Linux kernel versions prior to 5.17.1, update to version 5.17.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the jbd2 journal wait updates function until a patch is available.
