  "details": "In the Linux kernel, the following vulnerability has been resolved:  drm/dp/mst: fix OOB reads on 2-byte fields in sideband reply parsers  Three sideband reply parsers read 16-bit fields as:    val = (raw-\u003emsg[idx] \u003c\u003c 8) | (raw-\u003emsg[idx+1]);  and check bounds only after the fact. When idx == raw-\u003ecurlen, raw-\u003emsg[idx+1] reads one byte past the received message data into the following struct fields (curchunk_len, curchunk_idx, curlen).  Affected functions:  - drm_dp_sideband_parse_enum_path_resources_ack()    full_payload_bw_number and avail_payload_bw_number fields  - drm_dp_sideband_parse_allocate_payload_ack()    allocated_pbn field  - drm_dp_sideband_parse_query_payload_ack()    allocated_pbn field  Fix by using a single combined check (idx + 2 \u003e curlen) before each 2-byte read. Since the check is strictly tighter than idx \u003e curlen, no separate step is needed.  [added fixes tag]",
