Detailsinfo

A vulnerability, which was classified as critical, has been found in Linux Kernel up to 4.9.8 (Operating System). Affected by this issue is the function cp2112_gpio_direction_input of the file drivers/hid/hid-cp2112.c of the component EIO Error Handler. The manipulation with an unknown input leads to a 7pk error vulnerability. Using CWE to declare the problem leads to CWE-388. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The cp2112_gpio_direction_input function in drivers/hid/hid-cp2112.c in the Linux kernel 4.9.x before 4.9.9 does not have the expected EIO error status for a zero-length report, which allows local users to have an unspecified impact via unknown vectors.

The bug was discovered 04/16/2017. The weakness was presented 04/23/2017 (oss-sec). The advisory is available at openwall.com. This vulnerability is handled as CVE-2017-8072 since 04/23/2017. Local access is required to approach this attack. The successful exploitation requires a simple authentication. Technical details are known, but there is no available exploit.
