      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/dp/mst: fix OOB reads on 2-byte fields in sideband reply parsers\n\nThree sideband reply parsers read 16-bit fields as:\n\n  val = (raw->msg[idx] << 8) | (raw->msg[idx+1]);\n\nand check bounds only after the fact. When idx == raw->curlen,\nraw->msg[idx+1] reads one byte past the received message data into\nthe following struct fields (curchunk_len, curchunk_idx, curlen).\n\nAffected functions:\n - drm_dp_sideband_parse_enum_path_resources_ack()\n   full_payload_bw_number and avail_payload_bw_number fields\n - drm_dp_sideband_parse_allocate_payload_ack()\n   allocated_pbn field\n - drm_dp_sideband_parse_query_payload_ack()\n   allocated_pbn field\n\nFix by using a single combined check (idx + 2 > curlen) before each\n2-byte read. Since the check is strictly tighter than idx > curlen,\nno separate step is needed.\n\n[added fixes tag]",
