In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: fix shift-out-of-bounds in CalculateVMAndRowBytes
[WHY] When PTEBufferSizeInRequests is zero, UBSAN reports the following warning because dml_log2 returns an unexpected negative value:
shift exponent 4294966273 is too large for 32-bit type 'int'
[HOW]
In the case PTEBufferSizeInRequests is zero, skip the dml_log2() and assign the result directly.
