"The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2022:1213 advisory.
The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security Fix(es):
* kernel: remote stack overflow via kernel panic on systems using TIPC may lead to DoS (CVE-2022-0435)
* kernel: out-of-bounds read in in vc_do_resize function in drivers/tty/vt/vt.c (CVE-2020-8647)
* kernel: invalid read location in vgacon_invert_region function in drivers/video/console/vgacon.c
(CVE-2020-8649)
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.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
