USN-6031-1: Linux kernel (OEM) 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) It was discovered that the Integrity Measurement Architecture (IMA) implementation in the Linux kernel did not properly enforce policy in certain conditions. A privileged attacker could use this to bypass Kernel lockdown restrictions. (CVE-2022-21505) 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 a race condition existed in the SMSC UFX USB driver implementation in the Linux kernel, leading to a use-after-free vulnerability. A [ more… ]

USN-6030-1: Linux kernel (Qualcomm Snapdragon) 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) It was discovered that the System V IPC implementation in the Linux kernel did not properly handle large shared memory counts. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2021-3669) It was discovered that a use-after-free vulnerability existed in the SGI GRU driver in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-3424) Ziming Zhang discovered that the VMware Virtual GPU DRM driver in the Linux kernel contained an out-of-bounds write vulnerability. A local attacker could [ more… ]

USN-6029-1: Linux kernel 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) 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 [ more… ]

USN-6028-1: libxml2 vulnerabilities It was discovered that lixml2 incorrectly handled certain XML files. An attacker could possibly use this issue to cause a crash or execute arbitrary code. (CVE-2023-28484) It was discovered that libxml2 incorrectly handled certain XML files. An attacker could possibly use this issue to cause a crash. (CVE-2023-29469) Source: USN-6028-1: libxml2 vulnerabilities

USN-6027-1: Linux kernel 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) [ more… ]
