CVE-2026-53323

A flaw was found in the Linux kernel's Distributed Switch Architecture DSA subsystem. Redundant locking operations within the DSA conduit ethtool wrappers can lead to a deadlock. A local attacker can exploit this by using the ethtool -i command, causing the system to become unresponsive and...
