CVE-2026-31481

CVE-2026-31481 affects the Linux kernel tracing code. The issue arises from boot-time trigger frees not being drained when kthread creation fails, causing boot-time deferred entries to leak and a NULL pointer dereference that crashes the system. The fix drains the entire queued list synchronously...

CVE-2026-31481 tracing: Drain deferred trigger frees if kthread creation fails

In the Linux kernel, the following vulnerability has been resolved: tracing: Drain deferred trigger frees if kthread creation fails Boot-time trigger registration can fail before the trigger-data cleanup kthread exists. Deferring those frees until late init is fine, but the post-boot fallback mus...
