CVE-2026-74745

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A deadlock occurs in the bnxt driver when canceling an IRQ affinity notifier. The issue arises because unregistering IRQ affinity notifiers waits for the callback synchronously, while the driver acquires the netdev instance lock in the notifier to restart the queue and attempts to cancel the work under that same lock.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
