Description

The mq_open system call in Linux kernel 2.6.9, in certain situations, can decrement a counter twice ("double decrement") as a result of multiple calls to the mntput function when the dentry_open function call fails, which allows local users to cause a denial of service (panic) via unspecified attack vectors.

Affected products

Linux kernel: 2.6.9-2.6.20
