Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

CVE-2024-43853 (opens in a new tab)How to fix?
Upgrade torvalds/linux to version 4.19.321, 5.4.283, 5.10.225, 5.15.166, 6.1.103, 6.6.44, 6.10.3 or higher.
Overview
Affected versions of this package are vulnerable to Use After Free in the proc_cpuset_show function. An attacker can cause kernel memory disclosure, memory corruption, or system crash by repeatedly reading /proc/<pid>/cpuset while concurrent mount and unmount operations are performed on the cpuset cgroup hierarchy. This is only exploitable if an unprivileged local user can trigger repeated reads of the procfs file while privileged users perform mount or unmount actions on the cpuset cgroup v1 hierarchy.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
