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.

Affected products

Linux kernel: 2.6.12, 2.6.12-rc1, 2.6.12-rc4, 2.6.12-rc5, 2.6.12.1, 2.6.12.2 (+37)
