In the Linux kernel, the following vulnerability has been resolved:

nilfs2: fix use-after-free of timer for log writer thread

Patch series "nilfs2: fix log writer related issues".

This bug fix series covers three nilfs2 log writer-related issues, including a timer use-after-free issue and potential deadlock issue on unmount, and a potential freeze issue in event synchronization found during their analysis. Details are described in each commit log.

This patch (of 3):

A use-after-free issue has been reported regarding the timer sctimer on the nilfssc_info structure.

The problem is that even though it is used to wake up a sleeping log writer thread, sctimer is not shut down until the nilfssc_info structure is about to be freed, and is used regardless of the thread's lifetime.

Fix this issue by limiting the use of sc_timer only while the log writer thread is alive.
