Pending analysis
Type:
CWE-476
NULL Pointer Dereference
Publication date:

Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
phy: qcom-qmp-usb: Fix an NULL vs IS_ERR() bug<br />
<br />
The qmp_usb_iomap() helper function currently returns the raw result of<br />
devm_ioremap() for non-exclusive mappings. Since devm_ioremap() may return<br />
a NULL pointer and the caller only checks error pointers with IS_ERR(),<br />
NULL could bypass the check and lead to an invalid dereference.<br />
<br />
Fix the issue by checking if devm_ioremap() returns NULL. When it does,<br />
qmp_usb_iomap() now returns an error pointer via IOMEM_ERR_PTR(-ENOMEM),<br />
ensuring safe and consistent error handling.
