| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.50
Description
The issue is related to the
ta if load debugfs write() function in the drivers/gpu/drm/amd/amdgpu/amdgpu psp ta.c module of the Linux kernel's amdgpu driver. It involves a memory write beyond the allocated buffer, potentially allowing an attacker to impact the confidentiality, integrity, and availability of protected information. The vulnerability is resolved by adding TA binary size validation to avoid out-of-bounds writes.Recommendations
To resolve the issue, update the Linux kernel to version 6.6.50 or later. As a temporary workaround, consider restricting access to the vulnerable
amdgpu module to minimize the risk of exploitation.Exploit
