high Nessus Plugin ID 178119

Language:

Synopsis

The remote Red Hat host is missing a security update for kernel.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2023:4022 advisory.

 The kernel packages contain the Linux kernel, the core of any Linux operating system.

 Security Fix(es):

 * kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588)

 For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

 Bug Fix(es):

 * The iscsi target deadlocks when the same host acts as an initiator to itself (i.e. connects via 127.0.0.1) (BZ#2183540)

 * Double free issue in filelayout_alloc_commit_info (BZ#2212868)

 * RHEL 7.2: XFS inode cluster corruption (BZ#2213360)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
