+
+commit d6854daa67be623860f4e1873fd3d3c275aba4ed upstream.
+
+snd_usbmidi_get_ms_info() validates the internal MIDIStreaming endpoint
+descriptor size before using baAssocJackID[], but the descriptor walker can
+still return a class-specific endpoint descriptor whose bLength exceeds the
+remaining bytes in the endpoint-extra scan.
+
+That leaves later flexible-array reads bounded by bLength, but not by the
+remaining bytes in the endpoint-extra scan.
+
+Stop walking when bLength is zero or
+extends past the remaining endpoint-extra scan.
+
+Fixes: 5c6cd7021a05 ("ALSA: usb-audio: Fix case when USB MIDI interface has more than one extra endpoint descriptor")

+Subject: drm/i915: skip __i915_request_skip() for already signaled requests
+
+From: Sebastian Brzezinka <sebastian.brzezinka@intel.com>
+
+commit 4cfe4c0efbdcde742a47813180cc69b132d7598e upstream.
+
+After a GPU reset the HWSP is zeroed, so previously completed
+requests appear incomplete. If such a request is picked up during
+reset_rewind() and marked guilty, i915_request_set_error_once()
+returns early (fence already signaled), leaving fence.error without
+a fatal error code. The subsequent __i915_request_skip() then hits:
+```
+GEM_BUG_ON(!fatal_error(rq->fence.error))
+```
+
+Fixes a kernel BUG observed on Sandy Bridge (Gen6) during
+heartbeat-triggered engine resets.
+```
+kernel BUG at drivers/gpu/drm/i915/i915_request.c:556!
+RIP: __i915_request_skip+0x15e/0x1d0 [i915]

+intel_gt_reset+0x30d/0x5b0 [i915]
+heartbeat+0x516/0x530 [i915]
+```
+
+Guard __i915_request_skip() with i915_request_signaled(), if the
+fence is already signaled, the ring content is committed and there
+is nothing left to skip.

+Subject: libceph: Fix potential null-ptr-deref in decode_choose_args()
+
+From: Raphael Zimmer <raphael.zimmer@tu-ilmenau.de>
+
+commit 28b0a2ab8c82d0bbdeb8013029c67c978ce6e4bf upstream.
+
+A message of type CEPH_MSG_OSD_MAP contains an OSD map that itself
+contains a CRUSH map. When decoding this CRUSH map in crush_decode(), an
+array of max_buckets CRUSH buckets is decoded, where some indices may
+not refer to actual buckets and are therefore set to NULL. The received
+CRUSH map may optionally contain choose_args that get decoded in
+decode_choose_args(). When decoding a crush_choose_arg_map, a series of
+choose_args for different buckets is decoded, with the bucket_index
+being read from the incoming message. It is only checked that the bucket
+index does not exceed max_buckets, but not that it doesn't point to an
+index with a NULL bucket. If a (potentially corrupted) message contains
+a crush_choose_arg_map including such a bucket_index, a null pointer
+dereference may occur in the subsequent processing when attempting to
+access the bucket with the given index.
+
+This patch fixes the issue by extending the affected check. Now, it is
+only attempted to access the bucket if it is not NULL.

+Subject: libceph: Fix potential out-of-bounds access in crush_decode()
+
+From: Raphael Zimmer <raphael.zimmer@tu-ilmenau.de>
+
+commit 4c79fc2d598694bda845b46229c9d48b65042970 upstream.
+
+A message of type CEPH_MSG_OSD_MAP containing a crush map with at least
+one bucket has two fields holding the bucket algorithm. If the values
+in these two fields differ, an out-of-bounds access can occur. This is
+the case because the first algorithm field (alg) is used to allocate
+the correct amount of memory for a bucket of this type, while the second
+algorithm field inside the bucket (b->alg) is used in the subsequent
+processing.
+
+This patch fixes the issue by adding a check that compares alg and
+b->alg and aborts the processing in case they differ. Furthermore,
+b->alg is set to 0 in this case, because the destruction of the crush
+map also uses this field to determine the bucket type, which can again
+result in an out-of-bounds access when trying to free the memory pointed
+to by the fields of the bucket. To correctly free the memory allocated
+for the bucket in such a case, the corresponding call to kfree is moved
+from the algorithm-specific crush_destroy_bucket functions to the
+generic crush_destroy_bucket().

+Subject: libceph: Fix potential out-of-bounds access in osdmap_decode()
+
+From: Raphael Zimmer <raphael.zimmer@tu-ilmenau.de>
+
+commit 35d0ed82d03e5ee77ea4f31f20e29562a7721649 upstream.
+
+When decoding osd_state and osd_weight from an incoming osdmap in
+osdmap_decode(), both are decoded for each osd, i.e., map->max_osd
+times. The ceph_decode_need() check only accounts for
+sizeof(*map->osd_weight) once. This can potentially result in an
+out-of-bounds memory access if the incoming message is corrupted such
+that the max_osd value exceeds the actual content of the osdmap message.
+
+This patch fixes the issue by changing the corresponding part in the
+ceph_decode_need() check to account for
+map->max_osd*sizeof(*map->osd_weight).

+Subject: libceph: handle rbtree insertion error in decode_choose_args()
+
+From: Raphael Zimmer <raphael.zimmer@tu-ilmenau.de>
+
+commit d289478cfc0bcf81c7914200d6abdcb78bd04ded upstream.
+
+A message of type CEPH_MSG_OSD_MAP contains an OSD map that itself
+contains a CRUSH map. The received CRUSH map may optionally contain
+choose_args that get decoded in decode_choose_args(). In this function,
+num_choose_arg_maps is read from the message, and a corresponding number
+of crush_choose_arg_maps gets decoded afterwards. Each
+crush_choose_arg_map has a choose_args_index, which serves as the key
+when inserting it into the choose_args rbtree of the decoded crush_map.
+If a (potentially corrupted) message contains two crush_choose_arg_maps
+with the same index, the assertion in insert_choose_arg_map() triggers a
+kernel BUG when trying to insert the second crush_choose_arg_map.
+
+This patch fixes the issue by switching to the non-asserting rbtree
+insertion function and rejecting the message if the insertion fails.

+Subject: powerpc/warp: Fix error handling in pika_dtm_thread
+
+From: Ma Ke <make24@iscas.ac.cn>
+
+commit 108d7f951271cbd36ca36efc5e5d106966f5180c upstream.
+
+pika_dtm_thread() acquires client through of_find_i2c_device_by_node()
+but fails to release it in error handling path. This could result in a
+reference count leak, preventing proper cleanup and potentially
+leading to resource exhaustion. Add put_device() to release the
+reference in the error handling path.
+
+Found by code review.
