Details

Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux
kernel contained a race condition during device removal, leading to a use-
after-free vulnerability. A physically proximate attacker could possibly
use this to cause a denial of service (system crash). (CVE-2023-47233)

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...

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 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)

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)

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

After a standard system update you need to reboot your computer to make all the necessary changes.

Learn more about how to get the fixes.

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.

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

Ubuntu Release Package Version
20.04 focal linux-image-5.15.0-1058-intel-iotg –  5.15.0-1058.64~20.04.1
linux-image-intel –  5.15.0.1058.64~20.04.1
linux-image-intel-iotg –  5.15.0.1058.64~20.04.1
