https://notcve.org/view.php?id=CVE-2024-42106
In the Linux kernel, the following vulnerability has been resolved: inet_diag: Initialize pad field in struct inet_diag_req_v2 KMSAN reported uninit-value access in raw_lookup() [1]. Diag for raw sockets uses the pad field in struct inet_diag_req_v2 for the underlying protocol. This field corresponds to the sdiag_raw_protocol field in struct inet_diag_req_raw. inet_diag_get_exact_compat() converts inet_diag_req to inet_diag_req_v2, but leaves the pad field uninitialized. So the issue occurs when raw_lookup() accesses the sdiag_raw_protocol field. Fix this by initializing the pad field in inet_diag_get_exact_compat(). Also, do the same fix in inet_diag_dump_compat() to avoid the similar issue in the future.

CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-42105 – nilfs2: fix inode number range checks
https://notcve.org/view.php?id=CVE-2024-42105
In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix inode number range checks Patch series "nilfs2: fix potential issues related to reserved inodes". This series fixes one use-after-free issue reported by syzbot, caused by nilfs2's internal inode being exposed in the namespace on a corrupted filesystem, and a couple of flaws that cause problems if the starting number of non-reserved inodes written in the on-disk super block is intentionally (or corruptly) changed from its default value. This patch (of 3): In the current implementation of nilfs2, "nilfs->ns_first_ino", which gives the first non-reserved inode number, is read from the superblock, but its lower limit is not checked. As a result, if a number that overlaps with the inode number range of reserved inodes such as the root directory or metadata files is set in the super block parameter, the inode number test macros (NILFS_MDT_INODE and NILFS_VALID_INODE) will not function properly. In addition, these test macros use left bit-shift calculations using with the inode number as the shift count via the BIT macro, but the result of a shift calculation that exceeds the bit width of an integer is undefined in the C specification, so if "ns_first_ino" is set to a large value other than the default value NILFS_USER_INO (=11), the macros may potentially malfunction depending on the environment. Fix these issues by checking the lower bound of "nilfs->ns_first_ino" and by preventing bit shifts equal to or greater than the NILFS_USER_INO constant in the inode number test macros. Also, change the type of "ns_first_ino" from signed integer to unsigned integer to avoid the need for type casting in comparisons such as the lower bound check introduced this time. • https://git.kernel.org/stable/c/57235c3c88bb430043728d0d02f44a4efe386476 https://git.kernel.org/stable/c/08cab183a624ba71603f3754643ae11cab34dbc4 https://git.kernel.org/stable/c/731011ac6c37cbe97ece229fc6daa486276052c5 https://git.kernel.org/stable/c/3be4dcc8d7bea52ea41f87aa4bbf959efe7a5987 https://git.kernel.org/stable/c/fae1959d6ab2c52677b113935e36ab4e25df37ea https://git.kernel.org/stable/c/9194f8ca57527958bee207919458e372d638d783 https://git.kernel.org/stable/c/1c91058425a01131ea30dda6cf43c67b17884d6a https://git.kernel.org/stable/c/e2fec219a36e0993642844be0f3455135 •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-42104 – nilfs2: add missing check for inode numbers on directory entries
https://notcve.org/view.php?id=CVE-2024-42104
In the Linux kernel, the following vulnerability has been resolved: nilfs2: add missing check for inode numbers on directory entries Syzbot reported that mounting and unmounting a specific pattern of corrupted nilfs2 filesystem images causes a use-after-free of metadata file inodes, which triggers a kernel bug in lru_add_fn(). As Jan Kara pointed out, this is because the link count of a metadata file gets corrupted to 0, and nilfs_evict_inode(), which is called from iput(), tries to delete that inode (ifile inode in this case). The inconsistency occurs because directories containing the inode numbers of these metadata files that should not be visible in the namespace are read without checking. Fix this issue by treating the inode numbers of these internal files as errors in the sanity check helper when reading directory folios/pages. Also thanks to Hillf Danton and Matthew Wilcox for their initial mm-layer analysis. • https://git.kernel.org/stable/c/c33c2b0d92aa1c2262d999b2598ad6fbd53bd479 https://git.kernel.org/stable/c/07c176e7acc5579c133bb923ab21316d192d0a95 https://git.kernel.org/stable/c/2f2fa9cf7c3537958a82fbe8c8595a5eb0861ad7 https://git.kernel.org/stable/c/b11e8fb93ea5eefb2e4e719497ea177a58ff6131 https://git.kernel.org/stable/c/1b7d549ed2c1fa202c751b69423a0d3a6bd5a180 https://git.kernel.org/stable/c/3ab40870edb883b9633dc5cd55f5a2a11afa618d https://git.kernel.org/stable/c/265fff1a01cdc083aeaf0d934c929db5cc64aebf https://git.kernel.org/stable/c/bb76c6c274683c8570ad788f79d4b875b •
