Ubuntu Security Notice USN-6704-3
March 25, 2024
linux-oracle, linux-oracle-5.15 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-oracle-5.15: Linux kernel for Oracle Cloud systems
Details:
It was discovered that the NVIDIA Tegra XUSB pad controller driver in the
Linux kernel did not properly handle return values in certain error
conditions. A local attacker could use this to cause a denial of service
(system crash). (CVE-2023-23000)
Quentin Minster discovered that the KSMBD implementation in the Linux
kernel did not properly handle session setup requests. A remote attacker
could possibly use this to cause a denial of service (memory exhaustion).
(CVE-2023-32247)
Lonial Con discovered that the netfilter subsystem in the Linux kernel did
not properly handle element deactivation in certain cases, leading to a
use-after-free vulnerability. A local attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2024-1085)
Notselwyn discovered that the netfilter subsystem in the Linux kernel did
not properly handle verdict parameters in certain cases, leading to a use-
after-free vulnerability. A local attacker could use this to cause a denial
of service (system crash) or possibly execute arbitrary code.
(CVE-2024-1086)
It was discovered that a race condition existed in the SCSI Emulex
LightPulse Fibre Channel driver in the Linux kernel when unregistering FCF
and re-scanning an HBA FCF table, leading to a null pointer dereference
vulnerability. A local attacker could use this to cause a denial of service
(system crash). (CVE-2024-24855)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 22.04 LTS:
linux-image-5.15.0-1054-oracle 5.15.0-1054.60
linux-image-oracle-lts-22.04 5.15.0.1054.50
Ubuntu 20.04 LTS:
linux-image-5.15.0-1054-oracle 5.15.0-1054.60~20.04.1
linux-image-oracle 5.15.0.1054.60~20.04.1
After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
