CVE-2026-74636

A flaw was found in the Linux kernel. A race condition exists between the updateeventfields and eventdefinefields functions within the tracing subsystem. A local user, by loading specific modules, could exploit this unprotected access to kernel fields. This could lead to a kernel panic, resulting...

CVE-2026-74471

A flaw was found in the Linux kernel's tracing subsystem. The tracemoduleaddevents function does not properly check the return value of registerevent. If event registration fails, a pointer to an event can still be created and retained even after the associated module memory is freed. This can le...
