It was discovered that a race condition existed in the instruction emulator
of the Linux kernel on Arm 64-bit systems. A local attacker could use this
to cause a denial of service (system crash). (CVE-2022-20422)
Wei Chen discovered that a race condition existed in the TIPC protocol
implementation in the Linux kernel, leading to a null pointer dereference
vulnerability. A local attacker could use this to cause a denial of service
(system crash). (CVE-2023-1382)
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)
Daniele Antonioli discovered that the Secure Simple Pairing and Secure
Connections pairing in the Bluetooth protocol could allow an
unauthenticated user to complete authentication without pairing
credentials. A physically proximate attacker placed between two Bluetooth
devices could use this to subsequently impersonate one of the paired
devices. (CVE-2023-24023)
shanzhulig discovered that the DRM subsystem in the Linux kernel contained
a race condition when performing certain operation while handling driver
unload, leading to a use-after-free vulnerability. A local attacker could
use this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2023-51043)
It was discovered that a race condition existed in the Bluetooth subsystem
of the Linux kernel, leading to a use-after-free vulnerability. A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2023-51779)
It was discovered that the device mapper driver in the Linux kernel did not
properly validate target size during certain memory allocations. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2023-52429, CVE-2024-23851)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
– Architecture specifics;
– ACPI drivers;
– I2C subsystem;
– Media drivers;
– JFS file system;
– IPv4 Networking;
– Open vSwitch;
