CVE-2026-53091

The CVE-2026-53091 issue concerns the Linux kernel’s handling of GSO packet headers during qdisc_pkt_len_segs_init(). The root cause is that many ndo_start_xmit() paths assume headers are already in skb->head, while tso_build_hdr() may copy from skb->data, and qdisc_pkt_len_segs_init() diss...

CVE-2026-53091 net: pull headers in qdisc_pkt_len_segs_init()

In the Linux kernel, the following vulnerability has been resolved: net: pull headers in qdiscpktlensegsinit Most ndostartxmit methods expects headers of gso packets to be already in skb-head. net/core/tso.c users are particularly at risk, because tsobuildhdr does a memcpyhdr, skb-data, hdrlen;...

CVE-2026-53074

The CVE-2026-53074 issue affects the Linux kernel BPF test path: bpf_prog_test_run_skb may access IPv4/IPv6 headers (ip_hdr/ipv6_hdr) after eth_type_trans() when the test input only contains an Ethernet header. The fix folds IPv4/IPv6 header length checks into the existing protocol switch and ret...
