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 •

In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: fix null pointer dereference in nouveau_connector_get_modes In nouveau_connector_get_modes(), the return value of drm_mode_duplicate() is assigned to mode, which will lead to a possible NULL pointer dereference on failure of drm_mode_duplicate().

https://notcve.org/view.php?id=CVE-2023-52888
In the Linux kernel, the following vulnerability has been resolved: media: mediatek: vcodec: Only free buffer VA that is not NULL In the MediaTek vcodec driver, while mtk_vcodec_mem_free() is mostly called only when the buffer to free exists, there are some instances that didn't do the check and triggered warnings in practice. We believe those checks were forgotten unintentionally. Add the checks back to fix the warnings. • https://git.kernel.org/stable/c/5c217253c76c94f76d1df31d0bbdcb88dc07be91 https://git.kernel.org/stable/c/303d01082edaf817ee2df53a40dca9da637a2c04 https://git.kernel.org/stable/c/eb005c801ec70ff4307727bd3bd6e8280169ef32 •
CVSS: -EPSS: 0%CPEs: 5EXPL: 0CVE-2024-42098 – crypto: ecdh - explicitly zeroize private_key
https://notcve.org/view.php?id=CVE-2024-42098
In the Linux kernel, the following vulnerability has been resolved: crypto: ecdh - explicitly zeroize private_key private_key is overwritten with the key parameter passed in by the caller (if present), or alternatively a newly generated private key. However, it is possible that the caller provides a key (or the newly generated key) which is shorter than the previous key. In that scenario, some key material from the previous key would not be overwritten. The easiest solution is to explicitly zeroize the entire private_key array first. Note that this patch slightly changes the behavior of this function: previously, if the ecc_gen_privkey failed, the old private_key would remain. Now, the private_key is always zeroized. This behavior is consistent with the case where params.key is set and ecc_is_key_valid fails. • https://git.kernel.org/stable/c/39173b04abda87872b43c331468a4a14f8f05ce8 https://git.kernel.org/stable/c/fd7ef325911eba1b7191b83cb580463242f2090d https://git.kernel.org/stable/c/80575b252ab0358b7e93895b2a510beb3cb3f975 https://git.kernel.org/stable/c/d96187eb8e59b572a8e6a68b6a9837a867ea29df https://git.kernel.org/stable/c/73e5984e540a76a2ee1868b91590c922da8c24c9 •
