If the interrupt never\nadvances the transaction state, the loop can wait forever.\n\nReturn -ETIMEDOUT when the completion wait expires, propagate interrupted\nwaits, and make the I2C master_xfer callback return the first transfer\nerror instead of reporting a successful message count.","modified":"2026-11-04T14:27:18.770731243Z","published":"2026-10-23T11:37:43.338Z","related":["SUSE-SU-2026:5091-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98886.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/09a950950e7e4e74e021e60941c8e816ef1b4f71"},{"type":"WEB","url":"https://git.kernel.org/stable/c/15c6d7f7127a53b7312232178ecf03e5850161d2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/898d209157fe2a245f7d9fe28c5921037d8b5033"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8add43887cca1fe11a0ded62199ce726901d3f20"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9b5ce5c496efd20c1c662cedba88465d39ec1f93"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c268df0653ab07bafc3d191e74ea097e3d9b9e69"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f85e8224bd4e1a0939cbfe13a6220fbddf61127c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98886.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98886"},{"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":"1e585b52fd8ea59792634bc31d227eb3456af22e"},{"fixed":"09a950950e7e4e74e021e60941c8e816ef1b4f71"},{"fixed":"898d209157fe2a245f7d9fe28c5921037d8b5033"},{"fixed":"15c6d7f7127a53b7312232178ecf03e5850161d2"},{"fixed":"8add43887cca1fe11a0ded62199ce726901d3f20"},{"fixed":"f85e8224bd4e1a0939cbfe13a6220fbddf61127c"},{"fixed":"c268df0653ab07bafc3d191e74ea097e3d9b9e69"},{"fixed":"9b5ce5c496efd20c1c662cedba88465d39ec1f93"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98886.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1.0"},{"fixed":"5.10.271"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98886.json"}}],"schema_version":"1.9.2"}
