[PATCH openEuler-1.0-LTS] nilfs2: fix use-after-free of timer for log writer thread
by Guo Mengqi 03 Jul '24

03 Jul '24

From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> stable inclusion from stable-v4.19.316 commit 822ae5a8eac30478578a75f7e064f0584931bf2d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IA6S5D CVE: CVE-2024-38583 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit f5d4e04634c9cf68bdf23de08ada0bb92e8befe7 upstream. 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.
