CVE-2026-80689

A flaw was found in the Linux kernel's mmiotrace component. When the mmiotracearray is not initialized or is disabled, invoking mmiotracerw or mmiotracemapping can lead to a NULL pointer dereference. This can cause a system crash, resulting in a Denial of Service DoS...

CVE-2026-68175

A flaw was found in the Linux kernel's mmiotrace tracer. A local user could repeatedly read from the tracepipe file without fully completing the read operation. This improper handling of resource cleanup leads to a significant memory leak and leaves stale references. The continuous accumulation o...
