https://notcve.org/view.php?id=CVE-2024-46782
In the Linux kernel, the following vulnerability has been resolved: ila: call nf_unregister_net_hooks() sooner syzbot found an use-after-free Read in ila_nf_input [1] Issue here is that ila_xlat_exit_net() frees the rhashtable, then call nf_unregister_net_hooks(). It should be done in the reverse way, with a synchronize_rcu(). This is a good match for a pre_exit() method.

https://notcve.org/view.php?id=CVE-2024-46781
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 not freed. Fix this issue by cleaning up inodes that have read the recovery data if the recovery routine fails midway before the log writer starts. • https://git.kernel.org/stable/c/0f3e1c7f23f8a6f8224fa1d275381f6d9279ad4b https://git.kernel.org/stable/c/35a9a7a7d94662146396199b0cfd95f9517cdd14 https://git.kernel.org/stable/c/da02f9eb333333b2e4f25d2a14967cff785ac82e https://git.kernel.org/stable/c/07e4dc2fe000ab008bcfe90be4324ef56b5b4355 https://git.kernel.org/stable/c/8e2d1e9d93c4ec51354229361ac3373058529ec4 https://git.kernel.org/stable/c/ca92c4bff2833cb30d493b935168d6cccd5c805d https://git.kernel.org/stable/c/9d8c3a585d564d776ee60d4aabec59b404be7403 https://git.kernel.org/stable/c/1cf1f7e8cd47244fa947d357ef1f642d9 •

https://notcve.org/view.php?id=CVE-2024-46780
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". Some sysfs attribute show methods read this superblock buffer without the necessary mutual exclusion, which can cause problems with pointer dereferencing and memory access, so fix it. • https://git.kernel.org/stable/c/da7141fb78db915680616e15677539fc8140cf53 https://git.kernel.org/stable/c/b90beafac05931cbfcb6b1bd4f67c1923f47040e https://git.kernel.org/stable/c/ba97ba173f9625d5f34a986088979eae8b80d38e https://git.kernel.org/stable/c/157c0d94b4c40887329418c70ef4edd1a8d6b4ed https://git.kernel.org/stable/c/b14e7260bb691d7f563f61da07d61e3c8b59a614 https://git.kernel.org/stable/c/19cfeba0e4b8eda51484fcf8cf7d150418e1d880 https://git.kernel.org/stable/c/8c6e43b3d5f109cf9c61bc188fcc8175404e924f https://git.kernel.org/stable/c/962562d4c70c5cdeb4e955d63ff2017c4 •
