Last modified
CVE-2021-37600 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. An integer overflow in util-linux through 2.37.1 can potentially cause a buffer overflow if an attacker were able to use system resources in a way that leads to a large number in the /proc/sysvipc/sem file. NOTE: this is unexploitable in GNU C Library environments, and possibly in all realistic environments.. EPSS estimates a 0.66% chance of exploitation in the next 30 days.
