CWE-119
Bugzilla:
1525474: CVE-2017-17558 kernel: Unallocated memory access by malicious USB device via bNumInterfaces overflow
The usb_destroy_configuration() function, in 'drivers/usb/core/config.c' in the USB core subsystem, in the Linux kernel through 4.14.5 does not consider the maximum number of configurations and interfaces before attempting to release resources. This allows local users to cause a denial of service, due to out-of-bounds write access, or possibly have unspecified other impact via a crafted USB device. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.
