This was unveiled when platform_get_irq() had started WARN() on IRQ 0 that is supposed to be a Linux IRQ number (also known as vIRQ). Rework the driver to respect IRQ domain when creating each MFD device separately, as the domain is not the same for all of them.

[PATCH OLK-6.6] usb: gadget: u_serial: Fix the issue that gs_start_io crashed due to accessing null pointer
by Liu Mingrui 07 Jan '25

07 Jan '25

From: Lianqin Hu <hulianqin(a)vivo.com> stable inclusion from stable-v6.6.67 commit 8ca07a3d18f39b1669927ef536e485787e856df6 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAO8 CVE: CVE-2024-56670 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 4cfbca86f6a8b801f3254e0e3c8f2b1d2d64be2b upstream. Considering that in some extreme cases, when u_serial driver is accessed by multiple threads, Thread A is executing the open operation and calling the gs_open, Thread B is executing the disconnect operation and calling the gserial_disconnect function,The port->port_usb pointer will be set to NULL. E.g. Thread A Thread B gs_open() gadget_unbind_driver() gs_start_io() composite_disconnect() gs_start_rx() gserial_disconnect() ... ... spin_unlock(&port->port_lock) status = usb_ep_queue() spin_lock(&port->port_lock) spin_lock(&port->port_lock) port->port_usb = NULL gs_free_requests(port->port_usb->in) spin_unlock(&port->port_lock) Crash This causes thread A to access a null pointer (port->port_usb is null) when calling the gs_free_requests function, causing a crash. If port_usb is NULL, the release request will be skipped as it will be done by gserial_disconnect. So add a null pointer check to gs_start_io before attempting to access the value of the pointer port->port_usb.
