F5 Networks BIG-IP : Linux kernel vulnerability (SOL15984)

medium Nessus Plugin ID 80529
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The pn_recvmsg function in net/phonet/datagram.c in the Linux kernel before 3.12.4 updates a certain length value before ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel stack memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution SOL15984.
