Severity CVSS v4.0:
Pending analysis
Type:
CWE-476 NULL Pointer Dereference
Publication date:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> usb: roles: fix NULL pointer issue when put module&amp;#39;s reference<br /> <br /> In current design, usb role class driver will get usb_role_switch parent&amp;#39;s<br /> module reference after the user get usb_role_switch device and put the<br /> reference after the user put the usb_role_switch device. However, the<br /> parent device of usb_role_switch may be removed before the user put the<br /> usb_role_switch. If so, then, NULL pointer issue will be met when the user<br /> put the parent module&amp;#39;s reference.<br /> <br /> This will save the module pointer in structure of usb_role_switch. Then,<br /> we don&amp;#39;t need to find module by iterating long relations.
