AI-suggested
An official fix is available and should be applied. The vulnerability has been resolved in updated Linux kernel versions as listed. Users should update to the patched kernel versions provided by their Linux distribution vendors. No additional mitigation is required beyond applying the official patch.
Description
A vulnerability in the Linux kernel's Qualcomm QMP USB PHY driver was fixed by correcting error handling in the qmp_usb_iomap() helper function. The function previously returned a raw pointer from devm_ioremap() without properly checking for NULL, which could lead to an invalid dereference. The fix ensures that a NULL return from devm_ioremap() is converted into a proper error pointer, preventing unsafe behavior. This issue affects multiple Linux kernel versions and has been addressed in official updates.
