https://notcve.org/view.php?id=CVE-2024-41030
In the Linux kernel, the following vulnerability has been resolved: ksmbd: discard write access to the directory open may_open() does not allow a directory to be opened with the write access. However, some writing flags set by client result in adding write access on server, making ksmbd incompatible with FUSE file system. Simply, let's discard the write access when opening a directory. list_add corruption. next is NULL. ------------[ cut here ]------------ kernel BUG at lib/list_debug.c:26! pc : __list_add_valid+0x88/0xbc lr : __list_add_valid+0x88/0xbc Call trace: __list_add_valid+0x88/0xbc fuse_finish_open+0x11c/0x170 fuse_open_common+0x284/0x5e8 fuse_dir_open+0x14/0x24 do_dentry_open+0x2a4/0x4e0 dentry_open+0x50/0x80 smb2_open+0xbe4/0x15a4 handle_ksmbd_work+0x478/0x5ec process_one_work+0x1b4/0x448 worker_thread+0x25c/0x430 kthread+0x104/0x1d4 ret_from_fork+0x10/0x20 • https://git.kernel.org/stable/c/66cf853e1c7a2407f15d9f7aaa3e47d61745e361 https://git.kernel.org/stable/c/9e84b1ba5c98fb5c9f869c85db1d870354613baa https://git.kernel.org/stable/c/198498b2049c0f11f7670be6974570e02b0cc035 https://git.kernel.org/stable/c/e2e33caa5dc2eae7bddf88b22ce11ec3d760e5cd •

https://notcve.org/view.php?id=CVE-2024-41020
In the Linux kernel, the following vulnerability has been resolved: filelock: Fix fcntl/close race recovery compat path When I wrote commit 3cad1bc01041 ("filelock: Remove locks reliably when fcntl/close race is detected"), I missed that there are two copies of the code I was patching: The normal version, and the version for 64-bit offsets on 32-bit kernels. Thanks to Greg KH for stumbling over this while doing the stable backport... Apply exactly the same fix to the compat path for 32-bit kernels. An LSM can prevent the fcntl/close race cleanup path in fcntl_setlk() from working, leading to use-after-free read in lock_get_status() when reading /proc/locks. • https://git.kernel.org/stable/c/c293621bbf678a3d85e3ed721c3921c8a670610d https://git.kernel.org/stable/c/a561145f3ae973ebf3e0aee41624e92a6c5cb38d https://git.kernel.org/stable/c/4c43ad4ab41602201d34c66ac62130fe339d686f https://git.kernel.org/stable/c/911cc83e56a2de5a40758766c6a70d6998248860 https://git.kernel.org/stable/c/53e21cfa68a7d12de378b7116c75571f73e0dfa2 https://git.kernel.org/stable/c/f4d0775c6e2f1340ca0725f0337de149aaa989ca https://git.kernel.org/stable/c/73ae349534ebc377328e7d21891e589626c6e82c https://git.kernel.org/stable/c/5b0af8e4c70e4b884bb94ff5f0cd49ecf •

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Validate ff offset This adds sanity checks for ff offset. There is a check on rt->first_free at first, but walking through by ff without any check. If the second ff is a large offset. We may encounter an out-of-bound read. • https://git.kernel.org/stable/c/35652dfa8cc9a8a900ec0f1e0395781f94ffc5f0 https://git.kernel.org/stable/c/818a257428644b8873e79c44404d8fb6598d4440 https://git.kernel.org/stable/c/6ae7265a7b816879fd0203e83b5030d3720bbb7a https://git.kernel.org/stable/c/82c94e6a7bd116724738aa67eba6f5fedf3a3319 https://git.kernel.org/stable/c/617cf144c206f98978ec730b17159344fd147cb4 https://git.kernel.org/stable/c/50c47879650b4c97836a0086632b3a2e300b0f06 •

In the Linux kernel, the following vulnerability has been resolved: ocfs2: strict bound check before memcmp in ocfs2_xattr_find_entry() xattr in ocfs2 maybe 'non-indexed', which saved with additional space requested. It's better to check if the memory is out of bound before memcmp, although this possibility mainly comes from crafted poisonous images. • https://git.kernel.org/stable/c/57a3d89831fcaa2cdbe024b47c7c36d5a56c3637 https://git.kernel.org/stable/c/c031d286eceb82f72f8623b7f4abd2aa491bfb5e https://git.kernel.org/stable/c/cfb926051fab19b10d1e65976211f364aa820180 https://git.kernel.org/stable/c/c726dea9d0c806d64c26fcef483b1fb9474d8c5e https://git.kernel.org/stable/c/e4ffea01adf3323c821b6f37e9577d2d400adbaa https://git.kernel.org/stable/c/af77c4fc1871847b528d58b7fdafb4aa1f6a9262 •
