Commit 44c10138fd4b\n(\"PCI: Change all drivers to use pci_device->revision\") replaced a\nconfiguration-space read with direct access to the cached revision field,\nbut left that access after pci_dev_put(). The bridge may therefore be freed\nbefore its revision is read.\n\nRead the revision before dropping the reference.","published":"2026-09-03T08:21:49.526Z","modified":"2026-09-05T03:48:34.817987367Z","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/1268ca9418e2217f2b60705cf4a280b689b26678"},{"type":"WEB","url":"https://git.kernel.org/stable/c/56fd78c8c820f527f8003e379ab71004b2e79a44"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5ef87b1b4656d675440ceab32a56e69ad958d3a1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7700a31039cdc6715cb6cce7e7a664ee4e945f67"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a626dfca96041842053cf2d1efceb436c4cd8dcf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a837deeaa37cc3f0e8c4e5c096787047f272c956"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dc711fb137b33c12e6ca22b6a9c9b9f21d49e4de"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fa0dca89b4fb0909ffda7b9ab6051af33270f95e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80732.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80732"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-05T03:48:34.817987367Z"}}
