In Bluetooth driver, there is a possible out of bounds write due to an incorrect bounds check. This could lead to local escalation of privilege with User execution privileges needed. User interaction is not needed for exploitation. Patch ID: WCNCR00412257; Issue ID: MSV-3292.
Improper bounds checking (bounds check) in the Bluetooth driver allows out of bounds write to the allocated heap memory area. An attacker with standard user privileges can exploit this vulnerability without requiring any interaction from the victim. Successful heap memory overwrite can lead to gaining control over code execution in the system.
An attacker can achieve local privilege escalation (privilege escalation) to a higher level than a standard user. The vulnerability classified as CRITICAL indicates potentially complete compromise of system confidentiality, integrity, and availability.
