resolved:\n\ndrm/amd/display: Clamp HDMI HDCP2 rx_id_list read to buffer size\n\n[Why & How]\nDuring HDCP 2.x repeater authentication over HDMI, the driver reads the\nsink's RxStatus register and extracts a 10-bit message size field (max\nvalue 1023). This value is used as the read length for the ReceiverID\nlist without being clamped to the size of the destination buffer\nrx_id_list[177]. A malicious HDMI repeater could advertise a message\nsize larger than the buffer, causing an out-of-bounds write during the\nI2C read.\n\nClamp the read length in mod_hdcp_read_rx_id_list() to the size of the\nrx_id_list buffer, matching the approach already used in the DP branch.\n\n(cherry picked from commit 229212219e4247d9486f8ba41ef087358490be09)"}], "lastModified": "2026-07-07T16:51:48.147", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "047C25D4-CC7B-4FD9-B441-C8E72652C2D0", "versionEndExcluding": "5.10.259", "versionStartIncluding": "5.6"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "5E938CDF-D1C4-43D0-98DC-9E11B6B55801", "versionEndExcluding": "5.15.210", "versionStartIncluding": "5.11"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C4446623-5F2B-4DD8-8666-9FAAC285A757", "versionEndExcluding": "6.1.176", "versionStartIncluding": "5.16"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "9062F1CD-CAD6-4EA2-A73F-C06D4A887B8C", "versionEndExcluding": "6.6.143", "versionStartIncluding": "6.2"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "85421C0C-ABDE-4357-971C-67F9087DE1B9", "versionEndExcluding": "6.12.94", "versionStartIncluding": "6.7"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "389025D2-958D-41BD-BD96-70ED1033A9F3", "versionEndExcluding": "6.18.36", "versionStartIncluding": "6.13"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "6A64BF9F-3BCA-42FD-98CB-8F03474D2B1E", "versionEndExcluding": "7.0.13", "versionStartIncluding": "6.19"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:7.1:rc1:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B1EF7059-E670-45F4-B422-54C40FA86390"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:7.1:rc2:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "0D38F0BF-A728-4133-A358-D44A2F7EE6D6"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:7.1:rc3:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "EC732D08-5F7B-46D9-B154-E60C7F4F0A97"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:7.1:rc4:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E5910A9D-F60A-409A-B486-FE66BFEBA9B9"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:7.1:rc5:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "81DFF19E-9CF8-49C6-8C36-1E4038622933"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:7.1:rc6:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B0E8FC71-3952-444C-83E9-718DBBBEC615"}], "operator": "OR"}]}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
