Technical description

The fill_write_buffer function in sysfs/file.c in Linux kernel 2.6.12 up to versions before 2.6.17-rc1 does not zero terminate a buffer when a length of PAGE_SIZE or more is requested, which might allow local users to cause a denial of service (crash) by causing an out-of-bounds read.

If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
