CVE-2022-47522

HIGHCVSS 7.5/10EPSS 0.90%

Last modified

CVE-2022-47522 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. The IEEE 802.11 specifications through 802.11ax allow physically proximate attackers to intercept (possibly cleartext) target-destined frames by spoofing a target's MAC address, sending Power Save frames to the access point, and then sending other frames to the access point (such as authentication frames or re-association frames) to remove the target's original security context. This behavior occurs because the specifications do not require an access point to purge its transmit queue before removing a client's pairwise encryption key.. EPSS estimates a 0.90% chance of exploitation in the next 30 days.
