Background
The i2c: ismt package is a component of the Linux Kernel, which is responsible for managing the I2C bus communication protocol. The I2C bus is commonly used for connecting low-speed peripherals to a computer system. The ismt module within the i2c package provides support for Intel System Management Technology (ISMT) devices. These devices enable remote management and monitoring capabilities for Intel-based systems. However, a memory corruption vulnerability has been discovered in the ismt_access() function of the i2c: ismt package.
Vulnerability Detail
The memory corruption vulnerability in the ismt_access() function allows an attacker to corrupt memory, potentially leading to arbitrary code execution or system crashes. The vulnerability was introduced in version v5.11 of the Linux Kernel and was fixed in version v5.18.2. An attacker could exploit this vulnerability by sending specially crafted input to the affected function, triggering the memory corruption. The impact and attack plausibility of this vulnerability have not yet been proven.
How To Fix
