The failed atomic state will then be cleared by the\natomic core and intel_crtc_free_hw_state() can be called again for the\nsame state, dropping the same blob references again.\n\nClear the blob pointers after dropping the references so repeated cleanup\nof the same CRTC hw state is safe.\n\n(cherry picked from commit d5005addb5f68e8a0edce249506757bdc9e3d8c8)","state":0,"publishedAt":"2026-08-15T05:57:00.234+00:00","modifiedAt":"2026-10-16T18:55:24.968+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"unaffected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/gpu/drm/i915/display/intel_atomic.c\"\n ],\n \"versions\": [\n {\n \"version\": \"9a6cbb4a5c168e94a69a0cbec572b3738205232b\",\n \"lessThan\": \"164afa1a3af8e8c91b4a6d5fd7b79a44ec70abf0\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"8581466b827fdf0300a3e2e93900ddefd8240053\",\n \"lessThan\": \"2024940522ef451098c940ab0b82d647de5e5d9b\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"77fcf58df15edcf3f5b5421f24814fb72796def9\",\n \"lessThan\": \"ac554ad943610031a25795d6ef71316f6164c136\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"77fcf58df15edcf3f5b5421f24814fb72796def9\",\n \"lessThan\": \"31f077088e0faae6be8377741f356dea1b94ba46\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"674fc4a50b667be65c947d81af63a9367deafb5c\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"6.12.80\",\n \"lessThan\": \"6.12.97\",\n \"status\": \"affected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.21\",\n \"lessThan\": \"6.18.40\",\n \"status\": \"affected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.19.11\",\n \"lessThan\": \"6.20\",\n \"status\": \"affected\",\n \"versionType\": \"semver\"\n }\n ]\n }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"affected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/gpu/drm/i915/display/intel_atomic.c\"\n ],\n \"versions\": [\n {\n \"version\": \"7.0\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"7.0\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.97\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.40\",\n \"lessThanOrEqual\": \"6.18.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.1.5\",\n \"lessThanOrEqual\": \"7.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.2\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/164afa1a3af8e8c91b4a6d5fd7b79a44ec70abf0","https://git.kernel.org/stable/c/2024940522ef451098c940ab0b82d647de5e5d9b","https://git.kernel.org/stable/c/ac554ad943610031a25795d6ef71316f6164c136","https://git.kernel.org/stable/c/31f077088e0faae6be8377741f356dea1b94ba46"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-72452","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-72452","identifiers":["CVE-2026-72452"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
