In the Linux kernel, the following vulnerability has been resolved:
ALSA: FCP: Fix NULL pointer dereference in interface lookup
A malformed USB device can provide a vendor-specific interface without any endpoint descriptors. fcp_find_fc_interface() currently selects the first vendor-specific interface and reads endpoint 0 from it, without checking whether the interface actually has any endpoints.
When bNumEndpoints is zero, no endpoint array is allocated for the parsed alternate setting, so get_endpoint(..., 0) yields an invalid endpoint descriptor pointer. Dereferencing it through usb_endpoint_num() then triggers a NULL pointer dereference.
Skip vendor-specific interfaces that do not have any endpoints.
