What to do
AI-suggested
A fix has been implemented in the Linux kernel to check for a valid interrupt handler before using the irq and to fall back to polling mode if necessary. Users should apply the official Linux kernel updates containing this fix once available. Patch status is not explicitly confirmed in the input; check the Linux kernel advisory for current remediation guidance.
Description
A vulnerability in the Linux kernel's PHY device driver could cause nullptr exceptions in the interrupt service routine (ISR) if the interrupt handler is not valid. The issue is addressed by checking for a valid interrupt handler before using the interrupt or falling back to polling mode.
