Description Robert Buchholz (RETIRED) gentoo-dev 2008-10-30 22:20:49 UTC
CVE-2008-4302 (
  fs/splice.c in the splice subsystem in the Linux kernel before 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.
