Memory Leak Vulnerability in Linux Kernel Affects AMD Platform

CVE-2023-54320

What is CVE-2023-54320?

A memory leak vulnerability exists in the Linux kernel affecting AMD platforms. The vulnerability arises in the function amd_pmc_stb_debugfs_open_v2() when the STB debug mechanism is enabled. If the amd_pmc_send_cmd() function encounters a failure, the allocated memory buffer is not released properly, leading to a memory leak. This issue can potentially degrade system performance over time if not addressed.
