CVE-2009-0859: Linux Kernel

Medium severity, CVSS 4.7. EPSS: 0.4% chance of exploitation in the next 30 days.

The shm_get_stat function in ipc/shm.c in the shm subsystem in the Linux kernel before 2.6.28.5, when CONFIG_SHMEM is disabled, misinterprets the data type of an inode, which allows local users to cause a denial of service (system hang) via an SHM_INFO shmctl call, as demonstrated by running the ipcs program.

Affected products

• Linux Linux Kernel: up to and including 2.6.28.4
