CVE-2022-3028: Debian Linux

High severity, CVSS 7.0. EPSS: 0.2% chance of exploitation in the next 30 days.

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.
