Samsung Mobile Devices Use-After-Free

CVE-2022-22265 is a high-severity improper check or handling of exceptional conditions vulnerability in Samsung Mobile Devices from Samsung, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version SMR Jan-2022 Release 1 as the first without the flaw, so updating Samsung Mobile Devices to that release or later removes the exposure. CISA added it to the Known Exploited Vulnerabilities catalogue on September 18, 2023, which means attacks have been observed in the wild.
