USN-5809-1: Linux kernel (OEM) vulnerabilities Kyle Zeng discovered that the sysctl implementation in the Linux kernel contained a stack-based buffer overflow. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-4378) Tamás Koczka discovered that the Bluetooth L2CAP handshake implementation in the Linux kernel contained multiple use-after-free vulnerabilities. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-42896) It was discovered that an integer overflow vulnerability existed in the Bluetooth subsystem in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2022-45934) Source: USN-5809-1: Linux kernel (OEM) vulnerabilities

USN-5808-1: Linux kernel (IBM) vulnerabilities It was discovered that the NFSD implementation in the Linux kernel did not properly handle some RPC messages, leading to a buffer overflow. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-43945) Tamás Koczka discovered that the Bluetooth L2CAP handshake implementation in the Linux kernel contained multiple use-after-free vulnerabilities. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-42896) It was discovered that the Xen netback driver in the Linux kernel did not properly handle packets structured in certain ways. An attacker in a guest VM could possibly use this to cause a denial of service (host NIC availability). (CVE-2022-3643) It was discovered that an integer overflow vulnerability existed in the Bluetooth subsystem [ more… ]

USN-5807-1: libXpm vulnerabilities Martin Ettl discovered that libXpm incorrectly handled certain XPM files. If a user or automated system were tricked into opening a specially crafted XPM file, a remote attacker could possibly use this issue to cause libXpm to stop responding, resulting in a denial of service. (CVE-2022-44617) Marco Ivaldi discovered that libXpm incorrectly handled certain XPM files. If a user or automated system were tricked into opening a specially crafted XPM file, a remote attacker could possibly use this issue to cause libXpm to stop responding, resulting in a denial of service. (CVE-2022-46285) Alan Coopersmith discovered that libXpm incorrectly handled calling external helper binaries. If libXpm was being used by a setuid binary, a local attacker could possibly use this issue to escalate privileges. (CVE-2022-4883) Source: USN-5807-1: libXpm vulnerabilities
