Vulnerability details

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The __scm_destroy function in net/core/scm.c in the Linux kernel 2.6.27.4, 2.6.26, and earlier makes indirect recursive calls to itself through calls to the fput function, which allows local users to cause a denial of service (panic) via vectors related to sending an SCM_RIGHTS message through a UNIX domain socket and closing file descriptors.
