If pinctrl_pm_select_sleep_state() fails,\nthe runtime suspend is aborted but the clock remains disabled, causing\na system crash when the hardware is subsequently accessed.\n\nFix this by switching the pinctrl state before disabling the clock so\nthat a pinctrl failure leaves the clock enabled and the hardware\naccessible.\n\nIn i2c_imx_runtime_resume(), restore the pinctrl state back to sleep\nif clk_enable() fails to keep the consistent.","modified":"2026-07-08T08:13:46.456016605Z","published":"2026-07-01T13:32:22.276Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53340.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/8783fb8031799f1230997c16df8c8dce9fcd1841"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9fa82cf393bafc7bd7ca15c1d5cbd5b57ab9de1d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c8f5269c1bf505847bc7dbb92054594790114de6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53340.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53340"},{"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":"576eba03c99435380d155e5f71d5d7603b9178f6"},{"fixed":"9fa82cf393bafc7bd7ca15c1d5cbd5b57ab9de1d"},{"fixed":"c8f5269c1bf505847bc7dbb92054594790114de6"},{"fixed":"8783fb8031799f1230997c16df8c8dce9fcd1841"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53340.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.14.0"},{"fixed":"6.18.36"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.13"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53340.json"}}],"schema_version":"1.7.5"}
