Loading vulnerability…
CVE-2022-3028 is a race condition in the Linux kernel XFRM IP packet-transformation subsystem. Simultaneous invocations of xfrm_probe_algs can concurrently update availability fields in the authentication-algorithm list (aalg_list), potentially resulting in an out-of-bounds write or an out-of-bounds read. Data read beyond bounds may be copied into a socket, exposing kernel heap memory.
