CVE-2005-3356

Linux Kernel 2.6.9 - Denial of Service via mq_open Double Decrement

Title source: llm
STIX 2.1

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.
