CVE-2022-3028

kernel: race condition in xfrm_probe_algs can lead to OOB read/write

Published Aug 31, 2022 CVSS 3.1 · 7.0 High EPSS < 1% KEV · Not listed
Description
A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket.
