{"id":"CVE-2026-80930","summary":"tpm: tpm_i2c_nuvoton: disable IRQ on wait timeout","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ntpm: tpm_i2c_nuvoton: disable IRQ on wait timeout\n\ni2c_nuvoton_wait_for_stat() enables the IRQ before waiting for the\ninterrupt handler to report a status change. If the wait times out, or is\ninterrupted before the handler runs, the function returns without\nbalancing the enable_irq() call.\n\nDisable the IRQ before leaving the failed wait path. Also preserve an\ninterrupted wait's original error code instead of converting it to\n-ETIMEDOUT inside the helper.","modified":"2026-09-18T18:26:40.481324329Z","published":"2026-09-11T19:42:05.528Z","related":["openSUSE-SU-2026:11805-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80930.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/007c9e637e0e0b9d946b7f0e8a42f1f1aca48d7a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/07c2544a47da481043e945322b1bef71cdd7af79"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2c9147b2c0d75091ab451c2461d1c91788a7e60b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/705c4ed0643366963547b2616d53165f2519c81f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/73e89faee1f9b9119fa70b679058b045168ae633"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aee2296d09f6aeff41db369c6fd2dcaea3ee302c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b0dc3f18af01ba9f157b7d810cb22d3752d244ef"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cde2d927c29e82380851f209222256c607969a1f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80930.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80930"},{"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":"4c336e4b1556f4b722ba597bc6e3df786968a600"},{"fixed":"007c9e637e0e0b9d946b7f0e8a42f1f1aca48d7a"},{"fixed":"2c9147b2c0d75091ab451c2461d1c91788a7e60b"},{"fixed":"07c2544a47da481043e945322b1bef71cdd7af79"},{"fixed":"b0dc3f18af01ba9f157b7d810cb22d3752d244ef"},{"fixed":"73e89faee1f9b9119fa70b679058b045168ae633"},{"fixed":"cde2d927c29e82380851f209222256c607969a1f"},{"fixed":"aee2296d09f6aeff41db369c6fd2dcaea3ee302c"},{"fixed":"705c4ed0643366963547b2616d53165f2519c81f"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-80930.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.13.0"},{"fixed":"5.10.270"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.221"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.109"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.50"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-80930.json"}}],"schema_version":"1.9.0"}
