In the Linux kernel, the following vulnerability has been resolved:
usb: hub: Guard against accesses to uninitialized BOS descriptors
Many functions in drivers/usb/core/hub.c and drivers/usb/core/hub.h
access fields inside udev->bos without checking if it was allocated and
initialized. If usb_get_bos_descriptor() fails for whatever
reason, udev->bos will be NULL and those accesses will result in a
crash:

CVE-2023-52477 [MEDIUM] CWE-476 kernel: usb: hub: Guard against accesses to uninitialized BOS descriptors
kernel: usb: hub: Guard against accesses to uninitialized BOS descriptors
In the Linux kernel, the following vulnerability has been resolved:
usb: hub: Guard against accesses to uninitialized BOS descriptors
Many functions in drivers/usb/core/hub.c and drivers/usb/core/hub.h
access fields inside udev->bos without checking if it was allocated and
initialized. If usb_get_bos_descriptor() fails for whatever
reason, udev->bos will be NULL and those accesses will result in a
crash:
