{"id":"CVE-2026-53307","summary":"pinctrl: pinconf-generic: Fully validate 'pinmux' property","details":"In the Linux kernel, the following vulnerability has been resolved:\n\npinctrl: pinconf-generic: Fully validate 'pinmux' property\n\nThe pinconf_generic_parse_dt_pinmux() assumes that the 'pinmux' property\nis not empty when present. This might be not true. With that, the allocator\nwill give a special value in return and not NULL which lead to the crash\nwhen trying to access that (invalid) memory. Fix that by fully validating\n'pinmux' value, including its length.","modified":"2026-07-08T08:06:26.835471365Z","published":"2026-06-26T19:41:02.046Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53307.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/6476aac13805721e16439bd71f0e1703a4154517"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b7842b722169359e7ffe4b838d2496e9e72ac996"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c98324ea7849b6e5baa1774f71709b375a2c2f9e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53307.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53307"},{"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":"7112c05fff83e15726dd60a10248b76474e3cdf9"},{"fixed":"6476aac13805721e16439bd71f0e1703a4154517"},{"fixed":"b7842b722169359e7ffe4b838d2496e9e72ac996"},{"fixed":"c98324ea7849b6e5baa1774f71709b375a2c2f9e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53307.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.15.0"},{"fixed":"6.18.33"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53307.json"}}],"schema_version":"1.7.5"}
