CVE-2013-3236: Linux Kernel

Medium severity, CVSS 4.9. EPSS: 0.3% chance of exploitation in the next 30 days.

The vmci_transport_dgram_dequeue function in net/vmw_vsock/vmci_transport.c in the Linux kernel before 3.9-rc7 does not properly initialize a certain length variable, which allows local users to obtain sensitive information from kernel stack memory via a crafted recvmsg or recvfrom system call.

Affected products

• Linux Linux Kernel: up to and including 3.9; version 3.9 only
