Ubuntu Security Notice USN-6765-1
May 07, 2024

linux-oem-6.5 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-oem-6.5: Linux kernel for OEM systems

Details:

Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel
did not properly validate H2C PDU data, leading to a null pointer
dereference vulnerability. A remote attacker could use this to cause a
denial of service (system crash). (CVE-2023-6356, CVE-2023-6535,
CVE-2023-6536)

Sander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida
discovered that the Linux kernel mitigations for the initial Branch History
Injection vulnerability (CVE-2022-0001) were insufficient for Intel
processors. A local attacker could potentially use this to expose sensitive
information. (CVE-2024-2201)

Chenyuan Yang discovered that the RDS Protocol implementation in the Linux
kernel contained an out-of-bounds read vulnerability. An attacker could use
this to possibly cause a denial of service (system crash). (CVE-2024-23849)

It was discovered that a race condition existed in the Bluetooth subsystem
in the Linux kernel, leading to a null pointer dereference vulnerability. A
privileged local attacker could use this to possibly cause a denial of
service (system crash). (CVE-2024-24860)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 22.04 LTS
   linux-image-6.5.0-1022-oem      6.5.0-1022.23
   linux-image-oem-22.04           6.5.0.1022.24
   linux-image-oem-22.04a          6.5.0.1022.24
   linux-image-oem-22.04b          6.5.0.1022.24
   linux-image-oem-22.04c          6.5.0.1022.24
   linux-image-oem-22.04d          6.5.0.1022.24

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.
