CVE-2024-35890

Kernel crash via stale GRO socket reference

Published May 19, 2024 · Updated Aug 5, 2026

Denial of service in affected Linux kernel releases allows local users to crash the kernel via GRO fraglist packet processing. The skb_gro_receive and skb_gro_receive_list paths clear an aggregated packet destructor but leave its socket pointer attached, so later skb_segment_list reuse prevents the packet from being orphaned. A low-privileged local user must cause fraglist GRO traffic to be segmented; the resulting skb_orphan invariant violation triggers a kernel BUG and interrupts the host.
