CVE-2010-4256: Linux Kernel

Low severity, CVSS 2.1. EPSS: 0.4% chance of exploitation in the next 30 days.

The pipe_fcntl function in fs/pipe.c in the Linux kernel before 2.6.37 does not properly determine whether a file is a named pipe, which allows local users to cause a denial of service via an F_SETPIPE_SZ fcntl call.

Affected products

• Linux Linux Kernel: before 2.6.37 (fixed in 2.6.37)
