high Nessus Plugin ID 135910

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for kernel.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1524 advisory.

 - kernel: offset2lib allows for the stack guard page to be jumped over (CVE-2017-1000371)

 - kernel: rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel lacks a certain upper-bound check, leading to a buffer overflow (CVE-2019-17666)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL kernel package based on the guidance in RHSA-2020:1524.
