Exploitation Summary

EIP tracks 1 public exploit for CVE-2010-4249. PoCs published by Key Night.

AI-analyzed exploit summary This exploit leverages a kernel vulnerability via socketpair operations to create a denial-of-service condition by exhausting kernel file descriptors and CPU resources. The process becomes unkillable and consumes 100% CPU.

Description

The wait_for_unix_gc function in net/unix/garbage.c in the Linux kernel before 2.6.37-rc3-next-20101125 does not properly select times for garbage collection of inflight sockets, which allows local users to cause a denial of service (system hang) via crafted use of the socketpair and sendmsg system calls for SOCK_SEQPACKET sockets.
