https://notcve.org/view.php?id=CVE-2022-2873
An out-of-bounds memory access flaw was found in the Linux kernel Intel’s iSMT SMBus host controller driver in the way a user triggers the I2C_SMBUS_BLOCK_DATA (with the ioctl I2C_SMBUS) with malicious input data. This flaw allows a local user to crash the system. Se ha encontrado un fallo de acceso a memoria fuera de límites en el controlador de host iSMT SMBus del kernel de Linux, en la forma en que un usuario desencadena I2C_SMBUS_BLOCK_DATA (con el ioctl I2C_SMBUS) con datos de entrada maliciosos.
