CVE-2023-53043
7.8 · HIGHOverview
CVE-2023-53043 is a high-severity vulnerability affecting linux linux_kernel. It was published on May 2, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
arm64: dts: qcom: sc7280: Mark PCIe controller as cache coherent
If the controller is not marked as cache coherent, then kernel will
try to ensure coherency during dma-ops and that may cause data corruption.
So, mark the PCIe node as dma-coherent as the devices on PCIe bus are
cache coherent.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
