CVE-2024-46675 is a medium-severity vulnerability in the Linux kernel's USB core subsystem affecting the dwc3 driver on Exynos platforms. It involves the USB core potentially accessing an invalid event buffer address during runtime suspend, which can cause SMMU faults and other memory issues. The issue occurs due to improper clearing of the event buffer address when the USB core is still active. The vulnerability has been resolved by adding a status check before clearing the event buffer address during runtime suspend.
