Description

In the Linux kernel, the following vulnerability has been resolved: usb: roles: fix NULL pointer issue when put module's reference In current design, usb role class driver will get usb_role_switch parent's module reference after the user get usb_role_switch device and put the reference after the user put the usb_role_switch device. However, the parent device of usb_role_switch may be removed before the user put the usb_role_switch. If so, then, NULL pointer issue will be met when the user put the parent module's reference. This will save the module pointer in structure of usb_role_switch. Then, we don't need to find module by iterating long relations.

Affected configurations

• linux linux kernel (>= 4.19 < 5.10.211) • linux linux kernel (>= 5.11 < 5.15.150) • linux linux kernel (>= 5.16 < 6.1.80) • linux linux kernel (>= 6.2 < 6.6.19) • linux linux kernel (>= 6.7 < 6.7.7) • linux linux kernel 6.8 • debian debian linux 10.0
