Last modified Jun 16, 2026

CVE-2009-0935 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.27% chance of exploitation in the next 30 days.
