AV:L/AC:H/Au:S/C:C/I:C/A:C

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

Description: This issue resolves a critical lock within the iavf driver, eliminating error-prone logic associated with try locks. The resolution involves replacing the critical lock with a netdev lock where applicable, addressing potential deadlocks reported by Lockdep during Virtual Function (VF) removal and work cancellation. The changes extend the protected section of the iavf watchdog task() function to encompass more work scheduling and correct a misplaced comment within iavf reset task(). The initial patch addresses a deadlock during VF removal and a circular locking dependency detected during work cancellation.

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