CVE-2024-46786 – fscache: delete fscache_cookie_lru_timer when fscache exits to avoid UAF
https://notcve.org/view.php?id=CVE-2024-46786
18 Sep 2024 — In the Linux kernel, the following vulnerability has been resolved: fscache: delete fscache_cookie_lru_timer when fscache exits to avoid UAF The fscache_cookie_lru_timer is initialized when the fscache module is inserted, but is not deleted when the fscache module is removed. If timer_reduce() is called before removing the fscache module, the fscache_cookie_lru_timer will be added to the timer list of the current cpu. Afterwards, a use-after-free will be triggered in the softIRQ after removing the fscache m... • https://git.kernel.org/stable/c/12bb21a29c19aae50cfad4e2bb5c943108f34a7d •

18 Sep 2024 — In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix missing cleanup on rollforward recovery error In an error injection test of a routine for mount-time recovery, KASAN found a use-after-free bug. It turned out that if data recovery was performed using partial logs created by dsync writes, but an error occurred before starting the log writer to create a recovered checkpoint, the inodes whose data had been recovered were left in the ns_dirty_files list of the nilfs object and were... • https://git.kernel.org/stable/c/0f3e1c7f23f8a6f8224fa1d275381f6d9279ad4b •
CVE-2024-46780 – nilfs2: protect references to superblock parameters exposed in sysfs

18 Sep 2024 — In the Linux kernel, the following vulnerability has been resolved: nilfs2: protect references to superblock parameters exposed in sysfs The superblock buffers of nilfs2 can not only be overwritten at runtime for modifications/repairs, but they are also regularly swapped, replaced during resizing, and even abandoned when degrading to one side due to backing device issues. So, accessing them requires mutual exclusion using the reader/writer semaphore "nilfs->ns_sem".
