AI-suggested
A fix is available that changes the psp_copy_fw function to perform validation and return error codes, replacing unsafe memory operations with validated copies. Users should update to the patched Linux kernel versions that include this fix to mitigate the vulnerability.
Description
A vulnerability in the Linux kernel's AMDGPU DRM driver related to PSP firmware buffer handling has been resolved. The issue involved improper validation and copying of the PSP private firmware buffer, which could lead to incorrect memory operations. The fix changes the psp_copy_fw function to return error codes on failure conditions and replaces direct memory operations with this safer function.
