Details
William Zhao discovered that the Traffic Control (TC) subsystem in the
Linux kernel did not properly handle network packet retransmission in
certain situations. A local attacker could use this to cause a denial of
service (kernel deadlock). (CVE-2022-4269)
It was discovered that the TUN/TAP driver in the Linux kernel did not
properly initialize socket data. A local attacker could use this to cause a
denial of service (system crash). (CVE-2023-1076)
It was discovered that the Real-Time Scheduling Class implementation in the
Linux kernel contained a type confusion vulnerability in some situations. A
local attacker could use this to cause a denial of service (system crash).

It was discovered that the Real-Time Scheduling Class implementation in the
Linux kernel contained a type confusion vulnerability in some situations. A
local attacker could use this to cause a denial of service (system crash).
(CVE-2023-1077)
It was discovered that the ASUS HID driver in the Linux kernel did not
properly handle device removal, leading to a use-after-free vulnerability.
A local attacker with physical access could plug in a specially crafted USB
device to cause a denial of service (system crash). (CVE-2023-1079)
It was discovered that the Xircom PCMCIA network device driver in the Linux
kernel did not properly handle device removal events. A physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2023-1670)
It was discovered that a race condition existed in the Xen transport layer
implementation for the 9P file system protocol in the Linux kernel, leading
to a use-after-free vulnerability. A local attacker could use this to cause
a denial of service (guest crash) or expose sensitive information (guest
kernel memory). (CVE-2023-1859)
Jose Oliveira and Rodrigo Branco discovered that the Spectre Variant 2
mitigations with prctl syscall were insufficient in some situations. A
local attacker could possibly use this to expose sensitive information.
(CVE-2023-1998)
It was discovered that the BigBen Interactive Kids' gamepad driver in the
Linux kernel did not properly handle device removal, leading to a use-
after-free vulnerability. A local attacker with physical access could plug
in a specially crafted USB device to cause a denial of service (system
crash). (CVE-2023-25012)
It was discovered that a use-after-free vulnerability existed in the HFS+
file system implementation in the Linux kernel. A local attacker could
possibly use this to cause a denial of service (system crash).
(CVE-2023-2985)
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.The problem can be corrected by updating your system to the following package versions:
