CVE-2019-15879 is a high-severity vulnerability rated 7.4/10 on the CVSS scale. In FreeBSD 12.1-STABLE before r356908, 12.1-RELEASE before p5, 11.3-STABLE before r356908, and 11.3-RELEASE before p9, a race condition in the cryptodev module permitted a data structure in the kernel to be used after it was freed, allowing an unprivileged process can overwrite arbitrary kernel memory.. EPSS estimates a 0.66% chance of exploitation in the next 30 days.
