CVE-2022-49756

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> phy: usb: sunplus: Fix potential null-ptr-deref in sp_usb_phy_probe()<br /> <br /> sp_usb_phy_probe() will call platform_get_resource_byname() that may fail<br /> and return NULL. devm_ioremap() will use usbphy-&gt;moon4_res_mem-&gt;start as<br /> input, which may causes null-ptr-deref. Check the ret value of<br /> platform_get_resource_byname() to avoid the null-ptr-deref.
