Description

The inotify_read function in the Linux kernel 2.6.27 to 2.6.27.13, 2.6.28 to 2.6.28.2, and 2.6.29-rc3 allows local users to cause a denial of service (OOPS) via a read with an invalid address to an inotify instance, which causes the device's event list mutex to be unlocked twice and prevents proper synchronization of a data structure for the inotify instance.

Affected configurations

• linux linux kernel (>= 2.6.27 <= 2.6.27.13) • linux linux kernel (>= 2.6.28 <= 2.6.28.2) • linux linux kernel 2.6.29
