Title
clk: qcom: gcc-ipq5018: fix terminating of frequency table arrays
Summary
In the Linux kernel, the following vulnerability has been resolved: clk: qcom: gcc-ipq5018: fix terminating of frequency table arrays The frequency table arrays are supposed to be terminated with an empty element. Add such entry to the end of the arrays where it is missing in order to avoid possible out-of-bound access when the table is traversed by functions like qcom_find_freq() or qcom_find_freq_floor().
Severity

the affected RCGs are re-programmed by consumer drivers on paths an unprivileged local user can provoke (device-node open triggering runtime-PM resume on the USB/PCIe controllers, QPIC/NAND I/O), so basic local user privileges are sufficient rather than init-namespace root.\\nUI:N - The out-of-bounds walk occurs entirely within kernel clock-rate handling during normal driver operation;
