{"id":"USN-5789-1","summary":"linux-oem-5.14 vulnerabilities","details":"It was discovered that the NFSD implementation in the Linux kernel did not\nproperly handle some RPC messages, leading to a buffer overflow. A remote\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2022-43945)\n\nJann Horn discovered that the Linux kernel did not properly track memory\nallocations for anonymous VMA mappings in some situations, leading to\npotential data structure reuse. A local attacker could use this to cause a\ndenial of service (system crash) or possibly execute arbitrary code.\n(CVE-2022-42703)\n\nRoger Pau Monné discovered that the Xen virtual block driver in the Linux\nkernel did not properly initialize memory pages to be used for shared\ncommunication with the backend. A local attacker could use this to expose\nsensitive information (guest kernel memory). (CVE-2022-26365)\n\nJan Beulich discovered that the Xen network device frontend driver in the\nLinux kernel incorrectly handled socket buffers (skb) references when\ncommunicating with certain backends. A local attacker could use this to\ncause a denial of service (guest crash). (CVE-2022-33743)\n\nIt was discovered that a memory leak existed in the IPv6 implementation of\nthe Linux kernel. A local attacker could use this to cause a denial of\nservice (memory exhaustion). (CVE-2022-3524)\n\nIt was discovered that a race condition existed in the Bluetooth subsystem\nin the Linux kernel, leading to a use-after-free vulnerability. A local\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2022-3564)\n\nIt was discovered that the TCP implementation in the Linux kernel contained\na data race condition. An attacker could possibly use this to cause\nundesired behaviors. (CVE-2022-3566)\n\nIt was discovered that the IPv6 implementation in the Linux kernel\ncontained a data race condition. An attacker could possibly use this to\ncause undesired behaviors. (CVE-2022-3567)\n\nIt was discovered that the Realtek RTL8152 USB Ethernet adapter driver in\nthe Linux kernel did not properly handle certain error conditions. A local\nattacker with physical access could plug in a specially crafted USB device\nto cause a denial of service (memory exhaustion). (CVE-2022-3594)\n\nIt was discovered that a null pointer dereference existed in the NILFS2\nfile system implementation in the Linux kernel. A local attacker could use\nthis to cause a denial of service (system crash). (CVE-2022-3621)\n\n","modified":"2026-02-10T04:42:53Z","published":"2023-01-05T18:34:33Z","related":["UBUNTU-CVE-2022-26365","UBUNTU-CVE-2022-33743","UBUNTU-CVE-2022-3524","UBUNTU-CVE-2022-3564","UBUNTU-CVE-2022-3566","UBUNTU-CVE-2022-3567","UBUNTU-CVE-2022-3594","UBUNTU-CVE-2022-3621","UBUNTU-CVE-2022-42703","UBUNTU-CVE-2022-43945"],"upstream":["CVE-2022-26365","CVE-2022-33743","CVE-2022-3524","CVE-2022-3564","CVE-2022-3566","CVE-2022-3567","CVE-2022-3594","CVE-2022-3621","CVE-2022-42703","CVE-2022-43945","UBUNTU-CVE-2022-26365","UBUNTU-CVE-2022-33743","UBUNTU-CVE-2022-3524","UBUNTU-CVE-2022-3564","UBUNTU-CVE-2022-3566","UBUNTU-CVE-2022-3567","UBUNTU-CVE-2022-3594","UBUNTU-CVE-2022-3621","UBUNTU-CVE-2022-42703","UBUNTU-CVE-2022-43945"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-5789-1"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-3524"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-3564"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-3566"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-3567"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-3594"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-3621"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-26365"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-33743"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-42703"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-43945"}],"affected":[{"package":{"name":"linux-oem-5.14","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/linux-oem-5.14@5.14.0-1055.62?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.14.0-1055.62"}]}],"versions":["5.14.0-1004.4","5.14.0-1005.5","5.14.0-1007.7","5.14.0-1008.8","5.14.0-1010.10","5.14.0-1011.11","5.14.0-1013.13","5.14.0-1018.19","5.14.0-1020.22","5.14.0-1022.24","5.14.0-1024.26","5.14.0-1027.30","5.14.0-1029.32","5.14.0-1031.34","5.14.0-1032.35","5.14.0-1033.36","5.14.0-1034.37","5.14.0-1036.40","5.14.0-1038.42","5.14.0-1042.47","5.14.0-1044.49","5.14.0-1045.51","5.14.0-1046.53","5.14.0-1047.54","5.14.0-1048.55","5.14.0-1049.56","5.14.0-1050.57","5.14.0-1051.58","5.14.0-1052.59","5.14.0-1054.61"],"ecosystem_specific":{"availability":"No
