CVE-2026-45865
Description
A flaw was found in the Linux kernel's Message Control Transport Protocol (MCTP) over I2C (Inter-Integrated Circuit) implementation. A local attacker could exploit this vulnerability by performing I2C reads on an MCTP-I2C device. This could lead to the disclosure of uninitialized stack memory, potentially revealing sensitive information.
