CVE-2026-90146
CVE-2026-90146 is a Linux kernel vulnerability in the BPF/XDP subsystem. The root cause is that bpf_xdp_link_update() calls dev_xdp_install() directly, bypassing the validation checks in dev_xdp_attach(). This allows a local user with low privileges to create an XDP link with a normal program and...
