{"id":"CVE-2026-72260","summary":"ASoC: mediatek: mt8192: Check runtime resume during probe","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: mediatek: mt8192: Check runtime resume during probe\n\nThe MT8192 AFE probe enables runtime PM temporarily while reinitializing\nthe regmap cache from hardware, but it uses pm_runtime_get_sync()\nwithout checking the return value. If runtime resume fails, probe keeps\ngoing without the device necessarily being accessible, and\npm_runtime_get_sync() may leave the PM usage count incremented.\n\nThe regmap_reinit_cache() failure path also returns before dropping the\ntemporary PM reference and before clearing pm_runtime_bypass_reg_ctl.\n\nUse pm_runtime_resume_and_get() so resume failures do not leak a usage\ncount, and clear the temporary bypass flag after dropping the probe PM\nreference on all regmap_reinit_cache() outcomes.","modified":"2026-08-18T03:31:14.679460712Z","published":"2026-08-15T05:54:48.409Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72260.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/6e2ee6eacc3ec7b339753abcf33812d27e03efe5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e0f276f1918a202e9c3ac72baffd311cecb6b8db"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e24d5dde56a50946020b134fa8448869093db76a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f6e424835cc05d215c57b6370b2c1e353dd02915"},{"type":"WEB","url":"https://git.kernel.org/stable/c/faa97a1a6cab01cd3e2055deb4db4e57efc43ff2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72260.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72260"},{"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":"125ab5d588b0b3b842064c4d53a666ca74521ae8"},{"fixed":"6e2ee6eacc3ec7b339753abcf33812d27e03efe5"},{"fixed":"faa97a1a6cab01cd3e2055deb4db4e57efc43ff2"},{"fixed":"e0f276f1918a202e9c3ac72baffd311cecb6b8db"},{"fixed":"f6e424835cc05d215c57b6370b2c1e353dd02915"},{"fixed":"e24d5dde56a50946020b134fa8448869093db76a"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72260.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"6.6.148"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72260.json"}}],"schema_version":"1.9.0"}
