Summary

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 sc_timer on the nilfs_sc_info structure. The problem is that even though it is used to wake up a sleeping log writer thread, sc_timer is not shut down until the nilfs_sc_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.

Details are described in each commit log.\n\n\nThis patch (of 3):\n\nA use-after-free issue has been reported regarding the timer sc_timer on\nthe nilfs_sc_info structure.\n\nThe problem is that even though it is used to wake up a sleeping log\nwriter thread, sc_timer is not shut down until the nilfs_sc_info structure\nis about to be freed, and is used regardless of the thread\u0027s lifetime.\n\nFix this issue by limiting the use of sc_timer only while the log writer\nthread is alive."
