CVE-2005-3356: Linux Kernel

Low severity, CVSS 2.1. EPSS: 0.4% chance of exploitation in the next 30 days.

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 Linux Kernel: version 2.6.9 only
