I3C Bus Vulnerability in NPCM845 Linux Kernel by NXP

CVE-2026-97515

What is CVE-2026-97515?

A vulnerability in the Linux kernel related to the I3C bus on NPCM845 can lead to an IRQ storm when a device inaccurately triggers a Master Request. The system can enter a repeating cycle where a STOP condition inadvertently causes a new SLVSTART event, leading to endless interruptions that can freeze the CPU. By implementing a fix to clear the SLVSTART status bit after issuing a STOP command, this issue can be resolved effectively without disrupting the normal operations of the I3C bus.
