A device bound dynamically via sysfs can match the driver without that data, which leads to a NULL pointer dereference. Reject such matches before enabling the device. The Linux kernel CVE team has assigned CVE-2026-72147 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/dma/dw-edma/dw-edma-pcie.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/2733b5dcb5a4ba4446f7bac954b97e4501dcaa64 https://git.kernel.org/stable/c/a1042599fa8f9e313be176eb1ea1ae199f983419 https://git.kernel.org/stable/c/043acb00e4edd4b9ffb9dd0e357482dcd9086486 https://git.kernel.org/stable/c/044f7b3252d4fb2143d4999eec2800c08f1001ed https://git.kernel.org/stable/c/11d7cfe0c119691b2dafbb699bbca90258c678aa
