CVE-2026-53079

A flaw was found in the Linux kernel's networking scheduler netsched. When the network stack cleans up deferred packet lists, if the root queueing discipline qdisc does not implement the TCQFDEQUEUEDROPS flag, packets intended for release are not freed. This can lead to a memory leak, potentially...
