CVE-2011-1019
Public on
Last Modified:
Description
The CVE Program describes this issue as:
The dev_load function in net/core/dev.c in the Linux kernel before 2.6.38 allows local users to bypass an intended CAP_SYS_MODULE capability requirement and load arbitrary modules by leveraging the CAP_NET_ADMIN capability.
Statement
This issue did not affect the Linux kernel as shipped with Red Hat Enterprise Linux 4 and 5 as they did not backport the upstream commit a8f80e8f that introduced this flaw. This has been addressed in Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2011-0498.html and https://rhn.redhat.com/errata/RHSA-2011-0500.html.

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
