Ubuntu Security Notice USN-6871-1

linux-hwe-5.15 vulnerabilities
==========================================================================

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

- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-hwe-5.15: Linux hardware enablement (HWE) kernel

Details:

It was discovered that the ATA over Ethernet (AoE) driver in the Linux
kernel contained a race condition, leading to a use-after-free
vulnerability. An attacker could use this to cause a denial of service or
possibly execute arbitrary code. (CVE-2023-6270)

It was discovered that the Atheros 802.11ac wireless driver did not
properly validate certain data structures, leading to a NULL pointer
dereference. An attacker could possibly use this to cause a denial of
service. (CVE-2023-7042)

It was discovered that the HugeTLB file system component of the Linux
Kernel contained a NULL pointer dereference vulnerability. A privileged
attacker could possibly use this to to cause a denial of service.
(CVE-2024-0841)

It was discovered that the Intel Data Streaming and Intel Analytics
Accelerator drivers in the Linux kernel allowed direct access to the
devices for unprivileged users and virtual machines. A local attacker could
use this to cause a denial of service. (CVE-2024-21823)

Yuxuan Hu discovered that the Bluetooth RFCOMM protocol driver in the Linux
Kernel contained a race condition, leading to a NULL pointer dereference.
An attacker could possibly use this to cause a denial of service (system
crash). (CVE-2024-22099)

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 20.04 LTS
   linux-image-5.15.0-113-generic  5.15.0-113.123~20.04.1
   linux-image-5.15.0-113-generic-64k  5.15.0-113.123~20.04.1
   linux-image-5.15.0-113-generic-lpae  5.15.0-113.123~20.04.1
   linux-image-generic-64k-hwe-20.04  5.15.0.113.123~20.04.1
   linux-image-generic-hwe-20.04   5.15.0.113.123~20.04.1
   linux-image-generic-lpae-hwe-20.04  5.15.0.113.123~20.04.1
   linux-image-oem-20.04           5.15.0.113.123~20.04.1
   linux-image-oem-20.04b          5.15.0.113.123~20.04.1
   linux-image-oem-20.04c          5.15.0.113.123~20.04.1
   linux-image-oem-20.04d          5.15.0.113.123~20.04.1
   linux-image-virtual-hwe-20.04   5.15.0.113.123~20.04.1

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.
