Vulnerability from github – Published: 2024-08-21 09:31 – Updated: 2025-11-03 21:31In the Linux kernel, the following vulnerability has been resolved:
drm/i915/gt: Cleanup partial engine discovery failures
If we abort driver initialisation in the middle of gt/engine discovery, some engines will be fully setup and some not. Those incompletely setup engines only have 'engine->release == NULL' and so will leak any of the common objects allocated.
v2: - Drop the destroy_pinned_context() helper for now. It's not really worth it with just a single callsite at the moment. (Janusz)

Vulnerability from github – Published: 2024-04-02 09:30 – Updated: 2025-03-17 15:31In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dpu: check for valid hw_pp in dpu_encoder_helper_phys_cleanup
The commit 8b45a26f2ba9 ("drm/msm/dpu: reserve cdm blocks for writeback in case of YUV output") introduced a smatch warning about another conditional block in dpu_encoder_helper_phys_cleanup() which had assumed hw_pp will always be valid which may not necessarily be true.
Lets fix the other conditional block by making sure hw_pp is valid before dereferencing it.

[CAUSE] The first two lines of extra debug messages show the problem is caused by the error handling of run_delalloc_nocow().
E.g. we have the following dirtied range (4K blocksize 4K page size):
0 16K 32K
|//////////////////////////////////////|
| Pre-allocated |
And the range [0, 16K) has a preallocated extent.
-
Enter run_delalloc_nocow() for range [0, 16K) Which found range [0, 16K) is preallocated, can do the proper NOCOW write.
-
Enter fallback_to_fow() for range [16K, 32K) Since the range [16K, 32K) is not backed by preallocated extent, we have to go COW.
-
cow_file_range() failed for range [16K, 32K) So cow_file_range() will do the clean up by clearing folio dirty, unlock the folios.
Now the folios in range [16K, 32K) is unlocked.
- Enter extent_clear_unlock_delalloc() from run_delalloc_nocow() Which is called with PAGE_START_WRITEBACK to start page writeback. But folios can only be marked writeback when it's properly locked, thus this triggered the VM_BUG_ON_FOLIO().
Furthermore there is another hidden but common bug that run_delalloc_nocow() is not clearing the folio dirty flags in its error handling path. This is the common bug shared between run_delalloc_nocow() and cow_file_range().
[FIX] - Clear folio dirty for range [@start, @cur_offset) Introduce a helper, cleanup_dirty_folios(), which will find and lock the folio in the range, clear the dirty flag and start/end the writeback, with the extra handling for the @locked_folio.
-
Introduce a helper to clear folio dirty, start and end writeback
-
Introduce a helper to record the last failed COW range end This is to trace which range we should skip, to avoid double unlocking.
-
Skip the failed COW range for the e ---truncated---
