In the Linux kernel, the following vulnerability has been resolved:
gpu/buddy: bail out of try_harder when alignment cannot be honoured
The try_harder contiguous fallback could return a range whose start offset did not match the caller's min_block_size. When a candidate's start is misaligned, realign it: free the misaligned run and reallocate exactly @size at the next lower min_block_size boundary. This keeps the returned size unchanged with no surplus to trim, and rejects the request only when no aligned candidate fits.
v2: align misaligned candidates down to min_block_size instead of bailing out, for both the RHS and LHS paths (Matthew).
