- Summary
- phy: usb: sunplus: Fix potential null-ptr-deref in sp_usb_phy_probe()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
phy: usb: sunplus: Fix potential null-ptr-deref in spusbphy_probe()
spusbphyprobe() will call platformgetresourcebyname() that may fail and return NULL. devmioremap() will use usbphy->moon4resmem->start as input, which may causes null-ptr-deref. Check the ret value of platformgetresourcebyname() to avoid the null-ptr-deref.
