CVE-2024-26747 – usb: roles: fix NULL pointer issue when put module's reference
https://notcve.org/view.php?id=CVE-2024-26747
03 Apr 2024 — 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 mod... • https://git.kernel.org/stable/c/5c54fcac9a9de559b444ac63ec3cd82f1d157a0b • CWE-476: NULL Pointer Dereference •
