Kernel Vulnerability in Linux Affecting WCN7850 Devices

CVE-2025-38414

What is CVE-2025-38414?

A specific vulnerability exists in the Linux kernel that relates to the WCN7850 device, affecting its handling of the GCC_GCC_PCIE_HOT_RST definition. This misconfiguration can lead to kernel crashes on certain platforms when utilizing this particular hardware. The divergence in register definitions between WCN7850 and QCN9274 necessitated a revision of the register table, allowing for precise addresses and improved operation of the WCN7850. Devices not based on PCIe, such as the IPQ5332, are unaffected by this issue.
