CVE-2026-64349: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: fix dwc3_readl() and dwc3_writel() calls in dwc3_ulpi_setup() The dwc3_ulpi_setup() calls the register read and write calls with dwc3->regs when both these calls take the dwc3 structure directly. Chnage these two calls to fix the following sparse warning, and possibly a nasty bug in the dwc3_ulpi_setup() code: drivers/usb/dwc3/core.c:796:45: warning: incorrect type in argument 1 (different address spaces) drivers/usb/dwc3/core.c:796:45: expected struct dwc3 *dwc drivers/usb/dwc3/core.c:796:45: got void [noderef] __iomem *regs drivers/usb/dwc3/core.c:798:40: warning: incorrect type in argument 1 (different address spaces) drivers/usb/dwc3/core.c:798:40: expected struct dwc3 *dwc drivers/usb/dwc3/core.c:798:40: got void [noderef] __iomem *regs
