Updated kernel packages that fix two security issues, several bugs, and add
one enhancement are now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having Moderate security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.
The kernel packages contain the Linux kernel, the core of any Linux
* A flaw was found in the way the Linux kernel's VFS subsystem handled file
system locks. A local, unprivileged user could use this flaw to trigger a
deadlock in the kernel, causing a denial of service on the system.
* A buffer overflow flaw was found in the way the Linux kernel's virtio-net
subsystem handled certain fraglists when the GRO (Generic Receive Offload)
functionality was enabled in a bridged network configuration. An attacker
on the local network could potentially use this flaw to crash the system,
or, although unlikely, elevate their privileges on the system.
The CVE-2015-5156 issue was discovered by Jason Wang of Red Hat.
This update also fixes several bugs and adds one enhancement. Refer to the
following Knowledgebase article for further information:
All kernel users are advised to upgrade to these updated packages, which
