USN-6029-1

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 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)

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)
