A flaw was found in the Linux kernel's media: iris: gen2 component. When a session is stopped, a memory deallocation occurs. If a subsequent streaming stop operation is initiated without proper validation, it attempts to access already freed memory. This can be triggered by a local attacker or a malicious application, leading to a system crash and a Denial of Service (DoS).
