Detailsinfo

A vulnerability was found in Linux Kernel (Operating System) (unknown version). It has been rated as critical. Affected by this issue is the function ismt_access of the component Intel iSMT SMBus Host Controller Driver. The manipulation with an unknown input leads to a buffer overflow vulnerability. Using CWE to declare the problem leads to CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. Impacted is availability. CVE summarizes:

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.

The weakness was presented 09/09/2022 as 690b2549b19563ec5ad53e5c82f6a944d910086e. The advisory is available at github.com. This vulnerability is handled as CVE-2022-3077 since 09/01/2022. Technical details are known, but there is no available exploit.
