If\ni2c_add_adapter() fails, probe returns and devres frees the context,\nbut the PCI driver can still dereference the stale pointer from its IRQ\nand system-sleep callbacks.\n\nUnregister the callback before returning the adapter registration error.","published":"2026-08-28T06:52:48.300Z","modified":"2026-08-30T03:48:21.134955105Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"5.10.265"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1883a09a37fed497b9efacf736c23624a472246b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2f7789b3a9628819ebf90bcba8f9da3c139f8687"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4786d4d70dcd1e6b7e044f2348e00f201947b69c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/82048795242f04275a3f49ffc66ad851b6120954"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8bf719659406e4a1b56d441e0c7da2085d891d96"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9142a3dcff0d80a3a24ce159aee19ddc869d9784"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b7c2c5c8868737926410b93d1223ada17625ead3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cf107c5983dc70fcf932a305581a5f976d908ff1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80680.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80680"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-30T03:48:21.134955105Z"}}
