Description
The vulnerability allows a local user to cause memory corruption and potentially execute arbitrary code.
The vulnerability exists due to improper input validation in the AMDXDNA driver's ubuf size calculation when handling memory allocation requests. A local user can provide specially crafted input to trigger an integer overflow, resulting in an undersized allocation and subsequent memory corruption.
The attacker must have the ability to load or interact with the AMDXDNA driver, which typically requires user privileges on the system.
Remediation
Install security update from vendor's repository.
