CVE-2026-72057

In CVE-2026-72057, the Linux kernel net/sched code path act_ct is vulnerable due to tc_skb_cb not being preserved when defragmenting. The function tcf_ct_handle_fragments() calls nf_ct_handle_fragments() without saving/restoring skb->cb, and the defrag helper clears IPCB/IP6CB that alias the t...

CVE-2026-68337

A flaw was found in the Linux kernel. The BPF Berkeley Packet Filter redirect helpers, specifically bpfredirect and skbdoredirect, can attempt to dereference a null pointer if a bpfnetcontext is not established. This can occur when certain BPF programs are attached to a network queueing disciplin...
