GIGABYTE Multiple Products Unspecified

CVE-2018-19320 is a high-severity vulnerability in Aorus Graphics Engine from Gigabyte, 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 1.57 as the first without the flaw, so updating Aorus Graphics Engine to that release or later removes the exposure. CISA added it to the Known Exploited Vulnerabilities catalogue on October 24, 2022, which means attacks have been observed in the wild, including in ransomware campaigns.
