+Subject: [PATCH] mxfdemux: Store GstMXFDemuxEssenceTrack in their own fixed
+ allocation
+
+Previously they were stored inline inside a GArray, but as references to
+the tracks were stored in various other places although the array could
+still be updated (and reallocated!), this could lead to dangling
+references in various places.
+
+Instead now store them in a GPtrArray in their own allocation so each
+track's memory position stays fixed.
+
+Fixes ZDI-CAN-22299

+Subject: [PATCH 4/5] mxfdemux: Check number of channels for AES3 audio
+
+Only up to 8 channels are allowed and using a higher number would cause
+integer overflows when copying the data, and lead to out of bound
+writes.
+
+Also check that each buffer is at least 4 bytes long to avoid another
+overflow.

+Subject: [PATCH 5/5] h265parser: Fix possible overflow using
+ max_sub_layers_minus1
+
+This fixes a possible overflow that can be triggered by an invalid value of
+max_sub_layers_minus1 being set in the bitstream. The bitstream uses 3 bits,
+but the allowed range is 0 to 6 only.
