AI-suggested
A fix has been implemented in the Linux kernel to address this issue by changing the timing of flash parsing to avoid duplicate clock disables. Users should update to a Linux kernel version that includes this fix. Since this is a kernel-level issue, applying the official kernel update is the recommended remediation. No additional mitigation steps are indicated.
Description
A vulnerability in the Linux kernel's spi-cadence-quadspi driver was resolved. The issue involved duplicate clock disables triggered by runtime power management (PM) when device tree (DT) descriptions for attached flashes were missing or broken. This could cause warnings and potential instability during device probe. The fix involved moving flash parsing to an earlier stage to avoid redundant setup and clock disable conflicts.
