high Tenable Self-Hosted Container Security Plugin ID 458978

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to avoid use-after-free in
 f2fs_stop_gc_thread() syzbot reports a f2fs bug as below: __dump_stack lib/dump_stack.c:88 [inline]

 do_syscall_64+0xf3/0x230 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x77/0x7f The root
 cause is below race condition, it may cause use-after-free issue in sbi->gc_th pointer. - remount -
 f2fs_remount - f2fs_stop_gc_thread - kfree(gc_th) - f2fs_ioc_shutdown - f2fs_do_shutdown -
 f2fs_stop_gc_thread - kthread_stop(gc_th->f2fs_gc_task) : sbi->gc_thread = NULL; We will call
 f2fs_do_shutdown() in two paths: - for f2fs_ioc_shutdown() path, we should grab sb->s_umount semaphore for
 fixing. - for f2fs_shutdown() path, it's safe since caller has already grabbed sb->s_umount semaphore.
 (CVE-2024-47691)

Solution
