CVE-2026-80675

CVE-2026-80675 is a Linux kernel vulnerability in the libbpf signed loader . The loader verifies a map's SHA against a metadata hash in its instructions, but failed to ensure the map is exclusive . Without exclusivity, a hostile host could load another BPF program with map access to mutate the co...

CVE-2026-80675 libbpf: Reject non-exclusive metadata maps in the signed loader

In the Linux kernel, the following vulnerability has been resolved: libbpf: Reject non-exclusive metadata maps in the signed loader The loader verifies map-sha against the metadata hash in its instructions. map-sha is calculated when BPFOBJGETINFOBYFD is called on the frozen map. While the map is...

CVE-2026-80612

This Linux kernel vulnerability affects the net lwtunnel (lightweight tunnel) subsystem. When LWT encapsulation prepends outer headers, it moves skb->data over the headroom where XDP/TC skb metadata resides. Non-BPF encaps types (MPLS, Seg6, IOAM6) silently overwrite this metadata via skb_push...
