  "details": "In the Linux kernel, the following vulnerability has been resolved:  drm/dp/mst: fix OOB reads in remote DPCD/I2C sideband reply parsers  drm_dp_sideband_parse_remote_dpcd_read() reads num_bytes from the raw message and then unconditionally does:    memcpy(bytes, \u0026raw-\u003emsg[idx], num_bytes);  without checking that idx + num_bytes \u003c= raw-\u003ecurlen. raw-\u003emsg[] is 256 bytes; if a malicious or misbehaving MST hub sets num_bytes larger than the remaining payload, the memcpy reads past the received data into whatever follows in raw-\u003emsg[].  drm_dp_sideband_parse_remote_i2c_read_ack() has the same flaw (noted with a /* TODO check */ comment since the code was introduced).  Fix both functions by using a single combined check (idx + num_bytes \u003e curlen) before each memcpy. Since num_bytes is u8, it is always \u003e= 0, so this strictly subsumes the simpler idx \u003e curlen form and no separate step is needed.  [added missing fixes tag]",
