      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/dp/mst: fix OOB reads in remote DPCD/I2C sideband reply parsers\n\ndrm_dp_sideband_parse_remote_dpcd_read() reads num_bytes from the raw\nmessage and then unconditionally does:\n\n  memcpy(bytes, &raw->msg[idx], num_bytes);\n\nwithout checking that idx + num_bytes <= raw->curlen. raw->msg[] is\n256 bytes; if a malicious or misbehaving MST hub sets num_bytes larger\nthan the remaining payload, the memcpy reads past the received data\ninto whatever follows in raw->msg[].\n\ndrm_dp_sideband_parse_remote_i2c_read_ack() has the same flaw (noted\nwith a /* TODO check */ comment since the code was introduced).\n\nFix both functions by using a single combined check\n(idx + num_bytes > curlen) before each memcpy. Since num_bytes is u8,\nit is always >= 0, so this strictly subsumes the simpler idx > curlen\nform and no separate step is needed.\n\n[added missing fixes tag]",
