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-2026-46328 (opens in a new tab)How to fix?
Upgrade torvalds/linux to version 5.10.252, 5.15.202, 6.1.165, 6.6.128, 6.12.75, 6.18.14, 6.19.4 or higher.
Overview
Affected versions of this package are vulnerable to Improper Access Control in the __aa_transition_rlimits process. An attacker can bypass administrator-defined CPU usage constraints and potentially exhaust CPU resources or cause premature termination of confined services by executing a binary that triggers an AppArmor profile transition with differing RLIMIT_CPU rules.
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
