CVE-2009-3547

Multiple race conditions in fs/pipe.c in the Linux kernel before 2.6.32-rc6 allow local users to cause a denial of service (NULL pointer dereference and system crash) or gain privileges by attempting to open an anonymous pipe via a /proc/*/fd/ pathname.

HIGH 7.0EPSS 4.89%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (4.89%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
