No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

In the Linux kernel, the following vulnerability has been resolved:

bpf, xdp: move offload check into dev_xdp_install()

bpf_xdp_link_update() calls dev_xdp_install() directly and skips dev_xdp_attach(), so the checks in dev_xdp_attach() do not run. A user can make an XDP link with a normal program and then swap in an offloaded or device-bound program with BPF_LINK_UPDATE, which puts it on the software path.

dev_xdp_install() is the one place all three paths go through: "ip link set xdp" and BPF_LINK_CREATE reach it via dev_xdp_attach(), and BPF_LINK_UPDATE calls it directly. So move the program checks (offloaded, bound to another device, device-bound in generic mode, native vs generic, DEVMAP and CPUMAP) there, and keep only the netlink-flag check (XDP_FLAGS_UPDATE_IF_NOEXIST) in dev_xdp_attach().

No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
