Background

The drm/ttm package is a component of the Linux Kernel that provides support for graphics memory management. It is responsible for managing the transfer of data between the CPU and GPU. The ttm_transfered_destroy function within this package is vulnerable to a memory leak issue.

Vulnerability Detail

The vulnerability in ttm_transfered_destroy function can lead to a memory leak. When this function is called, it fails to release allocated memory, resulting in a gradual accumulation of unreleased memory. This can eventually lead to resource exhaustion and system instability. An attacker could potentially exploit this vulnerability to exhaust system resources and cause a denial-of-service (DoS) condition.
