🛡️ USN-6256-1 — linux-iot

linux-iot vulnerabilities

Jiasheng Jiang discovered that the HSA Linux kernel driver for AMD Radeon

GPU devices did not properly validate memory allocation in certain

situations, leading to a null pointer dereference vulnerability. A local

attacker could use this to cause a denial of service (system crash).

(CVE-2022-3108)

Zheng Wang discovered that the Intel i915 graphics driver in the Linux

kernel did not properly handle certain error conditions, leading to a

double-free. A local attacker could possibly use this to cause a denial of

service (system crash). (CVE-2022-3707)

It was discovered that the infrared transceiver USB driver did not properly

handle USB control messages. A local attacker with physical access could

plug in a specially crafted USB device to cause a denial of service (memory

exhaustion). (CVE-2022-3903)

Haowei Yan discovered that a race condition existed in the Layer 2

Tunneling Protocol (L2TP) implementation in the Linux kernel. A local

attacker could possibly use this to cause a denial of service (system

crash). (CVE-2022-4129)

Jordy Zomer and Alexandra Sandulescu discovered that syscalls invoking the

do_prlimit() function in the Linux kernel did not properly handle

speculative execution barriers. A local attacker could use this to expose

sensitive information (kernel memory). (CVE-2023-0458)

Jordy Zomer and Alexandra Sandulescu discovered that the Linux kernel did

not properly implement speculative execution barriers in usercopy functions

in certain situations. A local attacker could use this to expose sensitive

information (kernel memory). (CVE-2023-0459)

It was discovered that the Human Interface Device (HID) support driver 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-2023-1073)

It was discovered that a memory leak existed in the SCTP protocol

implementation in the Linux kernel. A local attacker could use this to

cause a denial of service (memory exhaustion). (CVE-2023-1074)

It was discovered that the TLS subsystem 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) or possibly expose

sensitive information. (CVE-2023-1075)

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 Reliable Datagram Sockets (RDS) protocol

implementation in the Linux kernel contained a type confusion vulnerability

in some situations. An attacker could use this to cause a denial of service

(system crash). (CVE-2023-1078)

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)

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)

It was discovered that the Traffic-Control Index (TCINDEX) implementation

in the Linux kernel contained 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-2023-1281)

It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux

kernel did not properly perform data buffer size validation in some

situations. A physically proximate attacker could use this to craft a

malicious USB device that when inserted, could cause a denial of service

(system crash) or possibly expose sensitive information. (CVE-2023-1380)

Xingyuan Mo discovered that the x86 KVM implementation in the Linux kernel

did not properly initialize some data structures. A local attacker could

use this to expose sensitive information (kernel memory). (CVE-2023-1513)

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 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 h
