Published Aug 26, 2026
·Updated
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
Recommended actions to resolve this vulnerability, in priority order.
- Configuration
In the Linux kernel, set the HDMA clock’s flag as critical (so it cannot be shut off) for the internal TCM access path of X100 RISC-V.
Linux kernel clk: spacemit (k3) HDMA clock flag (critical) = critical
