CVE-2017-16534 kernel: out-of-bounds read in cdc_parse_cdc_header function in drivers/usb/core/message.c
Last modified: 2018-02-12 04:01:15 EST
The cdc_parse_cdc_header() function in 'drivers/usb/core/message.c' in the Linux kernel before 4.13.6 allows local users to cause a denial of service (out-of-bounds read and system crash) 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.
