Background
The dm integrity package is a component of the Linux Kernel, which provides data integrity verification for block devices. It ensures the integrity of data by calculating and verifying cryptographic digests. This package is responsible for maintaining the integrity of data stored on block devices, such as hard drives and SSDs. However, a vulnerability has been discovered in the package that can lead to memory corruption.
Vulnerability Detail
The vulnerability in dm integrity occurs when the tag_size parameter is set to a value less than the digest size. This can result in memory corruption, potentially leading to system instability or unauthorized access to sensitive information. An attacker could exploit this vulnerability by manipulating the tag_size parameter to trigger the memory corruption. The impact and attack plausibility of this vulnerability have not been proven yet.
How To Fix
