CVE-2026-46328
Description
A flaw was found in the Linux kernel's AppArmor security module. The system's rlimit (resource limit) for POSIX (Portable Operating System Interface) CPU timers was not correctly enforced. This issue, stemming from an overlooked step in applying resource limits, could allow a local attacker to bypass intended CPU time restrictions, potentially leading to excessive resource consumption or a denial of service.
Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)
When allocating resources without limits, an attacker could prevent other systems, applications, or processes from accessing the same type of resource. It can be easy for an attacker to consume many resources by rapidly making many requests or causing larger resources to be used than is needed.
