The race is\npossible since the reader/parser doesn't hold any lock while accessing\nthe reception state. This in turn can lead to a memory corruption in the\nreader/parser as described by commit bd2fccac61b4 (\"drm/dp_mst: Fix MST\nsideband message body length check\").\n\nFix the above by resetting the message reception state if needed before\nreading/parsing a message. Another solution would be to hold the\ndrm_dp_mst_topology_mgr::lock for the whole duration of the message\nreception/parsing in drm_dp_mst_handle_down_rep() and\ndrm_dp_mst_handle_up_req(), however this would require a bigger change.\nSince the fix is also needed for stable, opting for the simpler solution\nin this patch." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/gpu/drm/display/drm_dp_mst_topology.c", "include/drm/display/drm_dp_mst_helper.h" ], "versions": [ { "version": "b30fcedeba643ca16eaa6212c1245598b7cd830d", "lessThan": "94b33b2d7640e807869451384eb88321dd0ffbd4", "status": "affected", "versionType": "git" }, { "version": "1d082618bbf3b6755b8cc68c0a8122af2842d593", "lessThan": "d834d20d2e86c52ed5cab41763fa61e6071680ef", "status": "affected", "versionType": "git" }, { "version": "1d082618bbf3b6755b8cc68c0a8122af2842d593", "lessThan": "be826b4451fd187a7c0b04be4f8243d5df6e0450", "status": "affected", "versionType": "git" }, { "version": "1d082618bbf3b6755b8cc68c0a8122af2842d593", "lessThan": "a6fa67d26de385c3c7a23c1e109a0e23bfda4ec7", "status": "affected", "versionType": "git" }, { "version": "ee4a4282d78d96e07e714c28ca54679713fa2157", "status": "affected", "versionType": "git" }, { "version": "db35e49413a4d03ea0c003598803e49956f59324", "status": "affected", "versionType": "git" }, { "version": "a579ed4613b5a64074963988ad481e43cf3b917b", "status": "affected", "versionType": "git" }, { "version": "6.1.18", "lessThan": "6.1.120", "status": "affected", "versionType": "semver" }, { "version": "5.10.173", "lessThan": "5.11", "status": "affected", "versionType": "semver" }, { "version": "5.15.100", "lessThan": "5.16", "status": "affected", "versionType": "semver" }, { "version": "6.2.5", "lessThan": "6.3", "status": "affected", "versionType": "semver" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/gpu/drm/display/drm_dp_mst_topology.c", "include/drm/display/drm_dp_mst_helper.h" ], "versions": [ { "version": "6.3", "status": "affected" }, { "version": "0", "lessThan": "6.3", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.120", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.66", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.5", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.13", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.1.18", "versionEndExcluding": "6.1.120" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.3", "versionEndExcluding": "6.6.66" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.3", "versionEndExcluding": "6.12.5" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.3", "versionEndExcluding": "6.13" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.10.173" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15.100" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.2.5" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/94b33b2d7640e807869451384eb88321dd0ffbd4" }, { "url": "https://git.kernel.org/stable/c/d834d20d2e86c52ed5cab41763fa61e6071680ef" }, { "url": "https://git.kernel.org/stable/c/be826b4451fd187a7c0b04be4f8243d5df6e0450" }, { "url": "https://git.kernel.org/stable/c/a6fa67d26de385c3c7a23c1e109a0e23bfda4ec7" } ], "title": "drm/dp_mst: Fix resetting msg rx state after topology removal", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "title": "CVE Program Container", "references": [ { "url": "https://lists.debian.org/debian-lts-announce/2025/03/msg00001.html" } ], "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T20:54:49.904Z" } } ] } }
