CVE-2020-25662 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. A Red Hat only CVE-2020-12352 regression issue was found in the way the Linux kernel's Bluetooth stack implementation handled the initialization of stack memory when handling certain AMP packets. This flaw allows a remote attacker in an adjacent range to leak small portions of stack memory on the system by sending specially crafted AMP packets. EPSS estimates a 1.17% chance of exploitation in the next 30 days.
