Last modified
CVE-2021-47620 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: Bluetooth: refactor malicious adv data check Check for out-of-bound read was being performed at the end of while num_reports loop, and would fill journal with false positives. Added check to beginning of loop processing so that it doesn't get checked after ptr has been advanced.. EPSS estimates a 0.22% chance of exploitation in the next 30 days.
