CVE-2026-43196

A flaw was found in the Linux kernel, specifically within the PRUSS (Programmable Real-time Unit Subsystem) clock multiplexer setup. This vulnerability, a double free, occurs when the system attempts to release the same memory resource twice. This can lead to memory corruption, which a local attacker could potentially exploit to cause the system to crash, resulting in a denial of service (DoS).

Red Hat acknowledges the upstream Linux kernel correction for «soc» as described in COMMENT_ZERO. Fixes are delivered through standard kernel errata for supported products. Operational exposure depends on whether this subsystem or driver is active in your configuration.
