CVE-2026-46021

A flaw was found in the Linux kernel's thermal management subsystem. This vulnerability can lead to a memory leak if a thermal governor is not correctly cleaned up during device registration failures. More critically, a race condition during thermal zone unregistration, where a governor update might conflict with the unregistration process, can result in a use-after-free error. A local attacker could potentially exploit this use-after-free to cause system instability, leading to a denial of service, or in some scenarios, achieve unauthorized code execution.
