Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. 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.
