CVE-2026-80523

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the spacemit k3 clock driver where the HDMA clock, which manages the internal TCM (Tightly Coupled Memory) access path of the X100 RISC-V core, is not marked as critical. This allows the clock to be shut off, which can lead to a system hang, specifically when a vector instruction access triggers a page fault.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
