Commit 44c10138fd4b ("PCI: Change all drivers to use pci_device->revision") replaced a configuration-space read with direct access to the cached revision field, but left that access after pci_dev_put(). The bridge may therefore be freed before its revision is read. Read the revision before dropping the reference. The Linux kernel CVE team has assigned CVE-2026-80732 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/ata/pata_sl82c105.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/1268ca9418e2217f2b60705cf4a280b689b26678 https://git.kernel.org/stable/c/a626dfca96041842053cf2d1efceb436c4cd8dcf https://git.kernel.org/stable/c/5ef87b1b4656d675440ceab32a56e69ad958d3a1 https://git.kernel.org/stable/c/fa0dca89b4fb0909ffda7b9ab6051af33270f95e https://git.kernel.org/stable/c/dc711fb137b33c12e6ca22b6a9c9b9f21d49e4de https://git.kernel.org/stable/c/a837deeaa37cc3f0e8c4e5c096787047f272c956 https://git.kernel.org/stable/c/56fd78c8c820f527f8003e379ab71004b2e79a44 https://git.kernel.org/stable/c/7700a31039cdc6715cb6cce7e7a664ee4e945f67
