Sources and claim methodology

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: clk: spacemit: k3: set hdma clock as critical HDMA clock is responsible for the internal TCM access path of X100 RISC-V core, so set the clock flag as critical to prevent it from being shut off, otherwise the Linux system will hang, for example in the case of a vector instruction access generates a page fault.
