So when driver unbind, this can trigger a use-after-free when DMA is torn down while the controller is still alive and triggers DMA transfers. The Linux kernel CVE team has assigned CVE-2026-74415 to this issue. Affected and fixed versions =========================== Issue introduced in 7.0 with commit 34e3815ea4597131d4324a4aa243d2201e672005 and fixed in 7.1.5 with commit af6a34c41683067a314d2b58b39edecb2e5e4ac6 Issue introduced in 7.0 with commit 34e3815ea4597131d4324a4aa243d2201e672005 and fixed in 7.2-rc1 with commit 565bdf45125a05aa8f622f58f598283f46ba43f4 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2026-74415 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/spi/spi-atcspi200.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/af6a34c41683067a314d2b58b39edecb2e5e4ac6 https://git.kernel.org/stable/c/565bdf45125a05aa8f622f58f598283f46ba43f4
