Title: Linux Kernel 'add_to_page_cache_lru()' Local Denial of Service Vulnerability

Severity: MODERATE

Description:

The Linux kernel is prone to a local denial-of-service vulnerability because of an error in the 'splice()' system call.

The problem occurs in the file 'fs/splice.c'. Specifically, when a call to 'add_to_page_cache_lru()' fails, the memory page in question will not be locked. However, the kernel will later try to release and unlock the page and will crash.

Attackers can exploit this issue to cause the kernel to crash, denying service to legitimate users.

This issue affects versions prior to Linux kernel 2.6.22.2.
