CVSS: 6.6EPSS: 0%CPEs: 5EXPL: 0CVE-2024-0607 – Kernel: nf_tables: pointer math issue in nft_byteorder_eval()
https://notcve.org/view.php?id=CVE-2024-0607
18 Jan 2024 — A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval() function, where the code iterates through a loop and writes to the `dst` array. On each iteration, 8 bytes are written, but `dst` is an array of u32, so each element only has space for 4 bytes. That means every iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local user to cause a denial of service or potentially break NetFilter functionality. • https://access.redhat.com/security/cve/CVE-2024-0607 • CWE-229: Improper Handling of Values •

11 Jan 2024 — A flaw was found in the blkgs destruction path in block/blk-cgroup.c in the Linux kernel, leading to a cgroup blkio memory leakage problem. When a cgroup is being destroyed, cgroup_rstat_flush() is only called at css_release_work_fn(), which is called when the blkcg reference count reaches 0. This circular dependency will prevent blkcg and some blkgs from being freed after they are made offline.
