CVE-2026-89487

CVE-2026-89487 affects the openvswitch subsystem in the Linux kernel. The bug resides in queue_userspace_packet(), whose error path calls skb_tx_error() on a packet that is still being forwarded through remaining flow actions. This call strips SKBFL_SHARED_FRAG from the live skb via skb_zcopy_cle...
