Linux Kernel Buffer Overflow Vulnerability in AMD GPU Driver via sysfs

A buffer overflow vulnerability has been identified in the Linux kernel's AMD GPU driver. The issue arises in the function 'smu_sys_set_pp_table()' when a malicious user provides a small power profile table (pptable) through the sysfs interface, followed by a larger one. This sequence can lead to a buffer overflow attack.

Impact

Exploitation of this vulnerability can lead to a buffer overflow, which may be exploited to execute arbitrary code or cause a denial-of-service condition.
