CVE-2024-49959

CVE-2024-49959 (Linux kernel) : The issue occurs in journaling code (jbd2). During journal space waits, __jbd2_log_wait_for_space() may call jbd2_cleanup_journal_tail() to reclaim space; if an error happens inside that cleanup (e.g., EIO) the function could keep waiting instead of stopping, poten...
