USN-6093-1: Linux kernel (BlueField) vulnerabilities
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) 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) Jordy Zomer and Alexandra Sandulescu discovered that syscalls invoking the doprlimit() 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) 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)
