Previously,\nset_output_gamma was being checked for null, but then it was being\ndereferenced without any null check. This could lead to a null pointer\ndereference if set_output_gamma is null.\n\nTo fix this, we now ensure that set_output_gamma is not null before\ndereferencing it. We do this by adding a null check for set_output_gamma\nbefore the call to set_output_gamma.",

  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: PCM: Fix wait queue list corruption in snd_pcm_drain() on linked streams\n\nsnd_pcm_drain() uses init_waitqueue_entry which does not clear\nentry.prev/next, and add_wait_queue with a conditional\nremove_wait_queue that is skipped when to_check is no longer\nin the group after concurrent UNLINK.  The orphaned wait entry\nremains on the unlinked substream sleep queue.  On the next\ndrain iteration, add_wait_queue adds the entry to a new queue\nwhile still linked on the old one, corrupting both lists.  A\nsubsequent wake_up dereferences NULL at the func pointer\n(mapped from the spinlock at offset 0 of the misinterpreted\nwait_queue_head_t), causing a kernel panic.\n\nReplace init_waitqueue_entry/add_wait_queue/conditional\nremove_wait_queue with init_wait_entry/prepare_to_wait/\nfinish_wait.  init_wait_entry clears prev/next via\nINIT_LIST_HEAD on each iteration and sets\nautoremove_wake_function which auto-removes the entry on\nwake-up.  finish_wait safely handles both the already-removed\nand still-queued cases.",

  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmm/migrate: fix shmem xarray update during migration\n\nA shmem folio can be either in page cache or in swap cache, but not at the\nsame time.  Namely, once it is in swap cache, folio-\u003emapping should be\nNULL, and the folio is no longer in a shmem mapping.\n\nIn __folio_migrate_mapping(), to determine the number of xarray entries to\nupdate, folio_test_swapbacked() is used, but that conflates shmem in page\ncache case and shmem in swap cache case.  It leads to xarray multi-index\nentry corruption, since it turns a sibling entry to a normal entry during\nxas_store() (see [1] for a userspace reproduction).  Fix it by only using\nfolio_test_swapcache() to determine whether xarray is storing swap cache\nentries or not to choose the right number of xarray entries to update.\n\n[1] https://lore.kernel.org/linux-mm/Z8idPCkaJW1IChjT@casper.infradead.org/\n\nNote:\nIn __split_huge_page(), folio_test_anon() \u0026\u0026 folio_test_swapcache() is\nused to get swap_cache address space, but that ignores the shmem folio in\nswap cache case.  It could lead to NULL pointer dereferencing when a\nin-swap-cache shmem folio is split at __xa_store(), since\n!folio_test_anon() is true and folio-\u003emapping is NULL.  But fortunately,\nits caller split_huge_page_to_list_to_order() bails out early with EBUSY\nwhen folio-\u003emapping is NULL.  So no need to take care of it here.",
