Description

The Linux Kernel contains a flaw that may allow a local denial of service. The issue is triggered when exactly or more than the platform processor's page size of data is written to a 'sysfs' file. Lack of termination of a buffer in the 'fill_write_buffer()' function will result in a kernel panic and hence in loss of availability for the platform.

Classification

Location: Local Access Required
Attack Type: Denial of Service
Impact: Loss of Availability
Exploit: Exploit Unknown
Disclosure: OSVDB Verified
