  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: cedrus: skip invalid H.264 reference list entries\n\nCedrus consumes H.264 ref_pic_list0/ref_pic_list1 entries from the\nstateless slice control and later uses their indices to look up\ndecode-\u003edpb[] in _cedrus_write_ref_list().\n\nRejecting such controls in cedrus_try_ctrl() would break existing\nuserspace, since stateless H.264 reference lists may legitimately carry\nout-of-range indices for missing references. Instead, guard the actual\nDPB lookup in Cedrus and skip entries whose indices do not fit the fixed\nV4L2_H264_NUM_DPB_ENTRIES array.\n\nThis keeps the fix local to the driver use site and avoids out-of-bounds\nreads from malformed or unsupported reference list entries.",
