CVE-2026-80850

CVE-2026-80850 is a use-after-free in the Linux kernel's TCP-AO implementation. During tcp_v4_connect(), a race exists between initial key validation and the later L3-master resolution in tcp_ao_connect_init(). If the bound network device is detached from its VRF in that window, the only AO key i...
