CVE-2024-53057

A flaw was found in the packet scheduler API in the Linux kernel. An invalid assumption about qdiscs with major handle ffff allows qdiscs, such as DRR, that maintain an active class list to cause a use-after-free with a dangling class pointer. Mitigation Mitigation for this issue is either not...
