CVE-2023-6931
Last modified
CVE-2023-6931 is a high-severity vulnerability rated 7/10 on the CVSS scale. A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be exploited to achieve local privilege escalation. A perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in perf_read_group(). We recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b.. EPSS estimates a 0.71% chance of exploitation in the next 30 days.
