Description

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).

Executive Summary

This vulnerability in the Linux kernel involves a flaw in the GPU buddy allocator's try_harder fallback mechanism. When the allocator cannot meet alignment requirements, it may return a memory range with an incorrect start offset. The fix ensures misaligned candidates are adjusted down to the minimum block size boundary instead of failing outright.

Impact Analysis

This vulnerability could lead to memory allocation failures in GPU operations, potentially causing system instability or crashes when applications request memory with specific alignment constraints. Users may experience graphical glitches or application errors.
