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...

CVE-2024-49959 jbd2: stop waiting for space when jbd2_cleanup_journal_tail() returns error

In the Linux kernel, the following vulnerability has been resolved: jbd2: stop waiting for space when jbd2cleanupjournaltail returns error In jbd2logwaitforspace, we might call jbd2cleanupjournaltail to recover some journal space. But if an error occurs while executing jbd2cleanupjournaltail e.g....
