Ubuntu Security Notice USN-6766-2
May 15, 2024

linux-hwe-5.15, linux-raspi 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-raspi: Linux kernel for Raspberry Pi systems
- linux-hwe-5.15: Linux hardware enablement (HWE) kernel

Details:

It was discovered that the Open vSwitch implementation in the Linux kernel
could overflow its stack during recursive action operations under certain
conditions. A local attacker could use this to cause a denial of service
(system crash). (CVE-2024-1151)

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)

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-5.15.0-1054-raspi   5.15.0-1054.57
   linux-image-raspi               5.15.0.1054.52
   linux-image-raspi-nolpae        5.15.0.1054.52

Ubuntu 20.04 LTS
   linux-image-5.15.0-106-generic  5.15.0-106.116~20.04.1
   linux-image-5.15.0-106-generic-64k  5.15.0-106.116~20.04.1
   linux-image-5.15.0-106-generic-lpae  5.15.0-106.116~20.04.1
   linux-image-generic-64k-hwe-20.04  5.15.0.106.116~20.04.1
   linux-image-generic-hwe-20.04   5.15.0.106.116~20.04.1
   linux-image-generic-lpae-hwe-20.04  5.15.0.106.116~20.04.1
   linux-image-oem-20.04           5.15.0.106.116~20.04.1
   linux-image-oem-20.04b          5.15.0.106.116~20.04.1
   linux-image-oem-20.04c          5.15.0.106.116~20.04.1
   linux-image-oem-20.04d          5.15.0.106.116~20.04.1
   linux-image-virtual-hwe-20.04   5.15.0.106.116~20.04.1

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.
