Description

linux, linux-aws, linux-aws-5.4, linux-azure, linux-azure-5.4, linux-gcp, linux-gcp-5.4, linux-gke, linux-gkeop, linux-hwe-5.4, linux-ibm, linux-ibm-5.4, linux-kvm, linux-oracle, linux-oracle-5.4, linux-raspi, linux-raspi-5.4 vulnerabilities

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)

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)

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)

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)

Lianhui Tang discovered that the MPLS implementation in the Linux kernel

did not properly handle certain sysctl allocation failure conditions,

leading to a double-free vulnerability. An attacker could use this to cause

a denial of service or possibly execute arbitrary code. (CVE-2023-26545)
