The pioctl for the OSD FS command in OpenAFS before 1.6.13 uses the wrong pointer when writing the results of the RPC, which allows local users to cause a denial of service (memory corruption and kernel panic) via a crafted OSD FS command.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
