CVE-2023-53043: In the Linux kernel, the following vulnerability has been resolved: arm64: dts: qcom: sc7280: Mark PCIe controller as c

CVE-2023-53043 is a bug in the Linux kernel where a PCIe controller (a hardware component that manages data transfer between a computer and devices connected via PCIe, a high-speed connection standard) was not marked as cache coherent (meaning the system wasn't told that data in the fast-access memory matches data in main memory). This could cause data corruption when the kernel tried to manage memory operations. The fix marks the PCIe node with the dma-coherent flag to tell the system that PCIe devices maintain cache coherency.
