Description

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.

Affected products

Linux kernel: through 2.6.27.4; 2.2.27, 2.4.36, 2.4.36.1, 2.4.36.2, 2.4.36.3, 2.4.36.4 (+94)
