CVE-2022-3028

HIGHCVSS 7/10EPSS 0.20%

Last modified

CVE-2022-3028 is a high-severity vulnerability rated 7/10 on the CVSS scale. 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.. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
