16 Jan 2024 — A memory leak flaw was found in the Linux kernel’s io_uring functionality in how a user registers a buffer ring with IORING_REGISTER_PBUF_RING, mmap() it, and then frees it. This flaw allows a local user to crash or potentially escalate their privileges on the system.

CVSS: 5.5EPSS: 0%CPEs: 10EXPL: 0CVE-2024-0443 – Kernel: blkio memory leakage due to blkcg and some blkgs are not freed after they are made offline.
https://notcve.org/view.php?id=CVE-2024-0443
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.
