{"id":"CVE-2026-23071","summary":"regmap: Fix race condition in hwspinlock irqsave routine","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nregmap: Fix race condition in hwspinlock irqsave routine\n\nPreviously, the address of the shared member '&map-\u003espinlock_flags' was\npassed directly to 'hwspin_lock_timeout_irqsave'. 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.","modified":"2026-04-02T17:29:50.304514Z","published":"2026-02-04T16:07:51.603Z","related":["SUSE-SU-2026:0962-1","SUSE-SU-2026:1081-1","SUSE-SU-2026:20667-1","SUSE-SU-2026:20720-1","SUSE-SU-2026:20838-1","SUSE-SU-2026:20845-1","SUSE-SU-2026:20876-1","SUSE-SU-2026:20931-1","openSUSE-SU-2026:20416-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23071.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/24f31be6ad70537fd7706269d99c92cade465a09"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4aab0ca0a0f7760e33edcb4e47576064d05128f5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4b58aac989c1e3fafb1c68a733811859df388250"},{"type":"WEB","url":"https://git.kernel.org/stable/c/766e243ae8c8b27087a4cc605752c0d5ee2daeab"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c2d2cf710dc3ee1a69e00b4ed8de607a92a07889"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e1a7072bc4f958c9e852dc7e57e39f12b0bb44b5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f1e2fe26a51eca95b41420af76d22c2e613efd5e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23071.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23071"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"8698b9364710e7bac84b3af07dd410e39c8c2e08"},{"fixed":"e1a7072bc4f958c9e852dc7e57e39f12b0bb44b5"},{"fixed":"766e243ae8c8b27087a4cc605752c0d5ee2daeab"},{"fixed":"f1e2fe26a51eca95b41420af76d22c2e613efd5e"},{"fixed":"24f31be6ad70537fd7706269d99c92cade465a09"},{"fixed":"4aab0ca0a0f7760e33edcb4e47576064d05128f5"},{"fixed":"c2d2cf710dc3ee1a69e00b4ed8de607a92a07889"},{"fixed":"4b58aac989c1e3fafb1c68a733811859df388250"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-23071.json"}}],"schema_version":"1.7.5"}
