USN-6033-1: Linux kernel (OEM) vulnerabilities

Read Time:3 Minute, 40 Second

It was discovered that the Traffic-Control Index (TCINDEX) implementation
in the Linux kernel did not properly perform filter deactivation in some
situations. A local attacker could possibly use this to gain elevated
privileges. Please note that with the fix for this CVE, kernel support for
the TCINDEX classifier has been removed. (CVE-2023-1829)

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)

Thadeu Cascardo discovered that the io_uring subsystem contained a double-
free vulnerability in certain memory allocation error conditions. A local
attacker could possibly use this to cause a denial of service (system
crash). (CVE-2023-1032)

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).
(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 io_uring subsystem in the Linux kernel did not
properly perform file table updates in some situations, leading to a null
pointer dereference vulnerability. A local attacker could use this to cause
a denial of service (system crash). (CVE-2023-1583)

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 the APM X-Gene SoC hardware monitoring driver in the
Linux kernel contained a race condition, leading to a use-after-free
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or expose sensitive information (kernel memory).
(CVE-2023-1855)

It was discovered that a race condition existed in the Bluetooth HCI SDIO
driver, leading to a use-after-free vulnerability. A local attacker could
use this to cause a denial of service (system crash). (CVE-2023-1989)

It was discovered that the ST NCI NFC driver did not properly handle device
removal events. A physically proximate attacker could use this to cause a
denial of service (system crash). (CVE-2023-1990)

José 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 race condition existed in the TLS subsystem in the
Linux kernel, leading to a use-after-free or a null pointer dereference
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-28466)

It was discovered that the Bluetooth subsystem in the Linux kernel did not
properly initialize some data structures, leading to an out-of-bounds
access vulnerability in certain situations. An attacker could use this to
expose sensitive information (kernel memory). (CVE-2023-28866)

Reima Ishii discovered that the nested KVM implementation for Intel x86
processors in the Linux kernel did not properly validate control registers
in certain situations. An attacker in a guest VM could use this to cause a
denial of service (guest crash). (CVE-2023-30456)

Duoming Zhou discovered that a race condition existed in the infrared
receiver/transceiver driver in the Linux kernel, leading to a use-after-
free vulnerability. A privileged attacker could use this to cause a denial
of service (system crash) or possibly execute arbitrary code.
(CVE-2023-1118)
