CVE-2008-4302 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.62% chance of exploitation in the next 30 days.
