{"id":"USN-6681-2","summary":"linux-bluefield, linux-raspi-5.4, linux-xilinx-zynqmp vulnerabilities","details":"Wenqing Liu discovered that the f2fs file system implementation in the\nLinux kernel did not properly validate inode types while performing garbage\ncollection. An attacker could use this to construct a malicious f2fs image\nthat, when mounted and operated on, could cause a denial of service (system\ncrash). (CVE-2021-44879)\n\nIt was discovered that the DesignWare USB3 for Qualcomm SoCs driver in the\nLinux kernel did not properly handle certain error conditions during device\nregistration. A local attacker could possibly use this to cause a denial of\nservice (system crash). (CVE-2023-22995)\n\nBien Pham discovered that the netfiler subsystem in the Linux kernel\ncontained a race condition, leading to a use-after-free vulnerability. A\nlocal user could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2023-4244)\n\nIt was discovered that a race condition existed in the Bluetooth subsystem\nof 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-2023-51779)\n\nIt was discovered that a race condition existed in the ATM (Asynchronous\nTransfer Mode) subsystem of the Linux kernel, leading to a use-after-free\nvulnerability. A local attacker could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code. (CVE-2023-51780)\n\nIt was discovered that a race condition existed in the Rose X.25 protocol\nimplementation in the Linux kernel, leading to a use-after- free\nvulnerability. A local attacker could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code. (CVE-2023-51782)\n\nAlon Zahavi discovered that the NVMe-oF/TCP subsystem of the Linux kernel\ndid not properly handle connect command payloads in certain situations,\nleading to an out-of-bounds read vulnerability. A remote attacker could use\nthis to expose sensitive information (kernel memory). (CVE-2023-6121)\n\nIt was discovered that the VirtIO subsystem in the Linux kernel did not\nproperly initialize memory in some situations. A local attacker could use\nthis to possibly expose sensitive information (kernel memory).\n(CVE-2024-0340)\n","modified":"2026-06-03T13:34:02.398260045Z","published":"2024-03-11T20:25:12Z","related":["UBUNTU-CVE-2021-44879","UBUNTU-CVE-2023-22995","UBUNTU-CVE-2023-4244","UBUNTU-CVE-2023-51779","UBUNTU-CVE-2023-51780","UBUNTU-CVE-2023-51782","UBUNTU-CVE-2023-6121","UBUNTU-CVE-2024-0340"],"upstream":["CVE-2021-44879","CVE-2023-22995","CVE-2023-4244","CVE-2023-51779","CVE-2023-51780","CVE-2023-51782","CVE-2023-6121","CVE-2024-0340","UBUNTU-CVE-2021-44879","UBUNTU-CVE-2023-22995","UBUNTU-CVE-2023-4244","UBUNTU-CVE-2023-51779","UBUNTU-CVE-2023-51780","UBUNTU-CVE-2023-51782","UBUNTU-CVE-2023-6121","UBUNTU-CVE-2024-0340"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6681-2"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2021-44879"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-4244"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-6121"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-22995"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-51779"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-51780"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-51782"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-0340"}],"affected":[{"package":{"name":"linux-raspi-5.4","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/linux-raspi-5.4?arch=source&distro=esm-infra%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.4.0-1104.116~18.04.1"}]}],"versions":["5.4.0-1013.13~18.04.1","5.4.0-1015.15~18.04.1","5.4.0-1016.17~18.04.1","5.4.0-1018.20~18.04.1","5.4.0-1019.21~18.04.1","5.4.0-1021.24~18.04.1","5.4.0-1022.25~18.04.1","5.4.0-1023.26~18.04.1","5.4.0-1025.28~18.04.1","5.4.0-1026.29~18.04.1","5.4.0-1028.31~18.04.1","5.4.0-1029.32~18.04.1","5.4.0-1030.33~18.04.1","5.4.0-1032.35~18.04.1","5.4.0-1033.36~18.04.1","5.4.0-1034.37~18.04.1","5.4.0-1035.38~18.04.1","5.4.0-1036.39~18.04.1","5.4.0-1038.41~18.04.1","5.4.0-1041.45~18.04.1","5.4.0-1042.46~18.04.3","5.4.0-1043.47~18.04.1","5.4.0-1044.48~18.04.1","5.4.0-1045.49~18.04.1","5.4.0-1046.50~18.04.1","5.4.0-1047.52~18.04.1","5.4.0-1048.53~18.04.1","5.4.0-1050.56~18.04.1","5.4.0-1052.58~18.04.1","5.4.0-1053.60~18.04.1","5.4.0-1055.62~18.04.1","5.4.0-1056.63~18.04.1","5.4.0-1058.65~18.04.1","5.4.0-1059.66~18.04.1","5.4.0-1060.68~18.04.1","5.4.0-1062.70~18.04.1","5.4.0-1065.75~18.04.1","5.4.0-1066.76~18.04.1","5.4.0-1068.78~18.04.1","5.4.0-1069.79~18.04.1","5.4.0-1070.80~18.04.1","5.4.0-1071.81~18.04.1","5.4.0-1073.84~18.04.1","5.4.0-1074.85~18.04.1","5.4.0-1077.88~18.04.2","5.4.0-1078.89~18.04.1","5.4.0-1079.90~18.04.1","5.4.0-1080.91~18.04.1","5.4.0-1081.92~18.04.1","5.4.0-1082.93~18.04.1","5.4.0-1083.94~18.04.1","5.4.0-1084.95~18.04.1","5.4.0-1085.96~18.04.1","5.4.0-1086.97~18.04.1","5.4.0-1088.99~18.04.1","5.4.0-1089.100~18.04.1","5.4.0-1090.101~18.04.1","5.4.0-1091.102~18.04.1","5.4.0-1092.103~18.04.1","5.4.0-1093.104~18.04.1","5.4.0-1094.105~18.04.1","5.4.0-1095.106~18.04.1","5.4.0-1096.107~18.04.1","5.4.0-1097.109~18.04.2","5.4.0-1098.110~18.04.2","5.4.0-1100.112~18.04.1","5.4.0-1101.113~18.04.1","5.4.0-1102.114~18.04.1","5.4.0-1103.115~18.04.1"],"ecosystem_specific":{"binaries":[{"binary_name":"linux-buildinfo-5.4.0-1104-raspi","binary_version":"5.4.0-1104.116~18.04.1"},{"binary_name":"linux-headers-5.4.0-1104-raspi","binary_version":"5.4.0-1104.116~18.04.1"},{"binary_name":"linux-image-5.4.0-1104-raspi","binary_version":"5.4.0-1104.116~18.04.1"},{"binary_name":"linux-modules-5.4.0-1104-raspi","binary_version":"5.4.0-1104.116~18.04.1"},{"binary_name":"linux-raspi-5.4-headers-5.4.0-1104","binary_version":"5.4.0-1104.116~18.04.1"},{"binary_version":"5.4.0-1104.116~18.04.1","binary_name":"linux-raspi-5.4-tools-5.4.0-1104"},{"binary_name":"linux-tools-5.4.0-1104-raspi","binary_version":"5.4.0-1104.116~18.04.1"}],"availability":"Available
