Last modified

CVE-2022-3077 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. A buffer overflow vulnerability was found in the Linux kernel Intel’s iSMT SMBus host controller driver in the way it handled the I2C_SMBUS_BLOCK_PROC_CALL case (via the ioctl I2C_SMBUS) with malicious input data. This flaw could allow a local user to crash the system.. EPSS estimates a 0.22% chance of exploitation in the next 30 days.
