{"id":"CVE-2026-80872","summary":"ALSA: hda/tas2781: Cancel async firmware request at unbind","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: hda/tas2781: Cancel async firmware request at unbind\n\nTAS2781 HDA I2C and SPI queue RCA firmware loading from component\nbind with request_firmware_nowait(). The firmware loader keeps the\ncallback module pinned and holds a device reference, but the callback\nstill uses driver-private HDA state.\n\nComponent unbind removes controls and DSP state immediately. Later\ndevice removal tears down the TAS2781 private data, including\ncodec_lock. If the async firmware callback runs after unbind has\nstarted, it can operate on state that is being torn down.\n\nCancel or synchronize the async firmware request before removing\ncontrols and DSP state. A queued callback is cancelled, and an\nalready-running callback is allowed to finish before unbind continues.","modified":"2026-09-06T03:46:55.410503140Z","published":"2026-09-04T16:48:37.011Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80872.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/5367e2ad14f0ae9350a7aaf2e77c87de39a43ae9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/da9e3be9cf31d7138d23e9e2f7ba1c102ef09f07"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f8272331da877eec8fe8e89a1e98e6a710e12490"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80872.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80872"},{"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":"5be27f1e3ec98975c18a91e220d4847d0dec9671"},{"fixed":"f8272331da877eec8fe8e89a1e98e6a710e12490"},{"fixed":"da9e3be9cf31d7138d23e9e2f7ba1c102ef09f07"},{"fixed":"5367e2ad14f0ae9350a7aaf2e77c87de39a43ae9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80872.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.6.0"},{"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-2026-80872.json"}}],"schema_version":"1.9.0"}
