This creates a race\ncondition where multiple contexts contending for the lock could overwrite\nthe shared flags variable, potentially corrupting the state for the\ncurrent lock owner.\n\nFix this by using a local stack variable 'flags' to store the IRQ state\ntemporarily.","state":0,"publishedAt":"2026-02-04T16:07:51.603+00:00","modifiedAt":"2026-10-19T18:25:29.039+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/base/regmap/regmap.c\"\n ],\n \"versions\": [\n {\n \"version\": \"8698b9364710e7bac84b3af07dd410e39c8c2e08\",\n \"lessThan\": \"e1a7072bc4f958c9e852dc7e57e39f12b0bb44b5\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"8698b9364710e7bac84b3af07dd410e39c8c2e08\",\n \"lessThan\": \"766e243ae8c8b27087a4cc605752c0d5ee2daeab\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"8698b9364710e7bac84b3af07dd410e39c8c2e08\",\n \"lessThan\": \"f1e2fe26a51eca95b41420af76d22c2e613efd5e\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"8698b9364710e7bac84b3af07dd410e39c8c2e08\",\n \"lessThan\": \"24f31be6ad70537fd7706269d99c92cade465a09\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"8698b9364710e7bac84b3af07dd410e39c8c2e08\",\n \"lessThan\": \"4aab0ca0a0f7760e33edcb4e47576064d05128f5\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"8698b9364710e7bac84b3af07dd410e39c8c2e08\",\n \"lessThan\": \"c2d2cf710dc3ee1a69e00b4ed8de607a92a07889\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"8698b9364710e7bac84b3af07dd410e39c8c2e08\",\n \"lessThan\": \"4b58aac989c1e3fafb1c68a733811859df388250\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\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/base/regmap/regmap.c\"\n ],\n \"versions\": [\n {\n \"version\": \"4.15\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"4.15\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.10.249\",\n \"lessThanOrEqual\": \"5.10.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.199\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.162\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.122\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.68\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.8\",\n \"lessThanOrEqual\": \"6.18.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.19\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/e1a7072bc4f958c9e852dc7e57e39f12b0bb44b5","https://git.kernel.org/stable/c/766e243ae8c8b27087a4cc605752c0d5ee2daeab","https://git.kernel.org/stable/c/f1e2fe26a51eca95b41420af76d22c2e613efd5e","https://git.kernel.org/stable/c/24f31be6ad70537fd7706269d99c92cade465a09","https://git.kernel.org/stable/c/4aab0ca0a0f7760e33edcb4e47576064d05128f5","https://git.kernel.org/stable/c/c2d2cf710dc3ee1a69e00b4ed8de607a92a07889","https://git.kernel.org/stable/c/4b58aac989c1e3fafb1c68a733811859df388250"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-23071","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-23071","identifiers":["CVE-2026-23071"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
