Ubuntu Security Notice USN-6898-2
July 17, 2024

linux-ibm-5.15, linux-lowlatency, linux-lowlatency-hwe-5.15,
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-lowlatency: Linux low latency kernel
- linux-ibm-5.15: Linux kernel for IBM cloud systems
- linux-lowlatency-hwe-5.15: Linux low latency kernel
- linux-oracle-5.15: Linux kernel for Oracle Cloud systems

Details:

Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not
properly handle certain error conditions, leading to a NULL pointer
dereference. A local attacker could possibly trigger this vulnerability to
cause a denial of service. (CVE-2022-38096)

Gui-Dong Han discovered that the software RAID driver in the Linux kernel
contained a race condition, leading to an integer overflow vulnerability. A
privileged attacker could possibly use this to cause a denial of service
(system crash). (CVE-2024-23307)

It was discovered that a race condition existed in the Bluetooth subsystem
in the Linux kernel when modifying certain settings values through debugfs.
A privileged local attacker could use this to cause a denial of service.
(CVE-2024-24857, CVE-2024-24858, CVE-2024-24859)

Bai Jiaju discovered that the Xceive XC4000 silicon tuner device driver in
the Linux kernel contained a race condition, leading to an integer overflow
vulnerability. An attacker could possibly use this to cause a denial of
service (system crash). (CVE-2024-24861)

Chenyuan Yang discovered that the Unsorted Block Images (UBI) flash device
volume management subsystem did not properly validate logical eraseblock
sizes in certain situations. An attacker could possibly use this to cause a
denial of service (system crash). (CVE-2024-25739)

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-5.15.0-116-lowlatency  5.15.0-116.126
  linux-image-5.15.0-116-lowlatency-64k  5.15.0-116.126
  linux-image-lowlatency          5.15.0.116.106
  linux-image-lowlatency-64k      5.15.0.116.106

Ubuntu 20.04 LTS
  linux-image-5.15.0-1058-ibm     5.15.0-1058.61~20.04.1
  linux-image-5.15.0-1063-oracle  5.15.0-1063.69~20.04.1
  linux-image-5.15.0-116-lowlatency  5.15.0-116.126~20.04.1
  linux-image-5.15.0-116-lowlatency-64k  5.15.0-116.126~20.04.1
  linux-image-ibm                 5.15.0.1058.61~20.04.1
  linux-image-lowlatency-64k-hwe-20.04  5.15.0.116.126~20.04.1
  linux-image-lowlatency-hwe-20.04  5.15.0.116.126~20.04.1
  linux-image-oracle              5.15.0.1063.69~20.04.1

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.
