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"}]},{"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"}}]}}
