A vulnerability classified as critical was found in Linux Kernel (Operating System) (unknown version). Affected by this vulnerability is an unknown code block of the component WLAN Driver. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability.

The weakness was shared 01/25/2016 as confirmed advisory (Website). It is possible to read the advisory at codeaurora.org. This vulnerability is known as CVE-2015-0569 since 01/07/2015. The exploitation appears to be easy. Attacking locally is a requirement. The exploitation doesn't need any form of authentication. It demands that the victim is doing some kind of user interaction. Technical details are unknown but a public exploit is available.

It is possible to download the exploit at exploit-db.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $5k-$25k. The code used by the exploit is:

memcpy(req.u.data.pointer, &p_req,
   sizeof(v_U8_t) * 3 +
   sizeof(struct PacketFilterParamsCfg) * 5);

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (110050) and Exploit-DB (39308). Additional details are provided at packetstormsecurity.com. The entries 80660, 80661, 83098 and 83089 are related to this item.
