CVE-2026-31499

A flaw was found in the Linux kernel's Bluetooth L2CAP component. A deadlock can occur in the l2capconndel function when canceling delayed work, specifically infotimer and idaddrtimer. This happens because l2capconndel holds a lock while attempting to cancel work functions that also acquire the...

CVE-2026-31480

A flaw was found in the Linux kernel. A local attacker or a user with specific privileges could exploit a race condition during CPU hotplug operations, specifically when using the 'osnoise' tracing feature. This vulnerability can lead to a system deadlock, rendering the system unresponsive and...
