ISS X-Force Database: linux-kernel-addtopagecachelru-dos(45191): Linux Kernel add_to_page_cache

Linux Kernel add_to_page_cache_lru() denial of service

linux-kernel-addtopagecachelru-dos (45191)

Low Risk

Description:

Linux Kernel is vulnerable to a denial of service, caused by an error in the splice() system call. The memory page remains unlocked during a failed call to the add_to_page_cache_lru() function. The kernel will attempt at a later time to release and unlock the currently open memory page. A local attacker could exploit this vulnerability to cause the kernel to crash.

*CVSS:

Base Score:	2.5
Access Vector:	Local
Access Complexity:	Low
Authentication:	Not Required
Confidentiality Impact:	None
Integrity Impact:	None
Availability Impact:	Partial

Temporal Score:	1.8
Exploitability:	Unproven
Remediation Level:	Official-Fix
Report Confidence:	Confirmed

Consequences:

Denial of Service

Remedy:

Upgrade to the latest version of Linux Kernel (2.6.22.2 or later), available from The Linux Kernel Archives Web site. See References.

BID-31201: Linux Kernel 'add_to_page_cache_lru()' Local Denial of Service Vulnerability
CVE-2008-4302: fs/splice.c in the splice subsystem in the Linux kernel before 2.6.22.2 does not properly handle a failure of the add_to_page_cache_lru function, and subsequently attempts to unlock a page that was not locked, which allows local users to cause a denial of service (kernel BUG and system crash), as demonstrated by the fio I/O tool.
