[Errata Announcements for Oracle Linux]

Synopsis: OVMSA-2024-0014 can now be patched using Ksplice
CVEs: CVE-2022-24448

Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle VM Security Fix Advisory, OVMSA-2024-0014.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running UEKR4 4.1.12 on
OL6 and OL7 install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* Denial-of-service in virtio SCSI driver.

A missing check when retrieving SCSI request in the virtio SCSI driver
could lead to a NULL pointer dereference. A local attacker could use
this flaw to cause a denial-of-service.


* Revert fix for CVE-2022-24448.

The original fix for this CVE introduces a regression leading to a
kernel panic. Oracle has elected not to issue a replacement rebootless
fix for this issue, as its impact is relatively low.
