A local attacker could use this to expose\nsensitive information (kernel memory). (CVE-2023-0458)\n\nIt was discovered that a race condition existed in the btrfs file system\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 expose sensitive information. (CVE-2023-1611)\n\nIt was discovered that the XFS file system implementation in the Linux\nkernel did not properly perform metadata validation when mounting certain\nimages. An attacker could use this to specially craft a file system image\nthat, when mounted, could cause a denial of service (system crash).\n(CVE-2023-2124)\n\nIt was discovered that a use-after-free vulnerability existed in the iSCSI\nTCP implementation in the Linux kernel. A local attacker could possibly use\nthis to cause a denial of service (system crash). (CVE-2023-2162)\n\nIt was discovered that the ext4 file system implementation in the Linux\nkernel did not properly handle extra inode size for extended attributes,\nleading to a use-after-free vulnerability. A privileged attacker could\npossibly use this to cause a denial of service (system crash) or possibly\nexecute arbitrary code. (CVE-2023-2513)\n\nIt was discovered that the IP-VLAN network driver for the Linux kernel did\nnot properly initialize memory in some situations, leading to an out-of-\nbounds write vulnerability. An attacker could use this to cause a denial of\nservice (system crash) or possibly execute arbitrary code. (CVE-2023-3090)\n\nIt was discovered that the Ricoh R5C592 MemoryStick card reader driver in\nthe Linux kernel contained a race condition during module unload, leading\nto a use-after-free vulnerability. A local attacker could use this to cause\na denial of service (system crash) or possibly execute arbitrary code.\n(CVE-2023-3141)\n\nIt was discovered that a use-after-free vulnerability existed in the IEEE\n1394 (Firewire) implementation in the Linux kernel. A privileged attacker\ncould use this to cause a denial of service (system crash) or possibly\nexecute arbitrary code. (CVE-2023-3159)\n\nSanan Hasanov discovered that the framebuffer console driver in the Linux\nkernel did not properly perform checks for font dimension limits. A local\nattacker could use this to cause a denial of service (system crash).\n(CVE-2023-3161)\n\nIt was discovered that the kernel->user space relay implementation in the\nLinux kernel did not properly perform certain buffer calculations, leading\nto an out-of-bounds read vulnerability. A local attacker could use this to\ncause a denial of service (system crash) or expose sensitive information\n(kernel memory). (CVE-2023-3268)\n\nIt was discovered that the netfilter subsystem in the Linux kernel did not\nproperly handle some error conditions, 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-2023-3390)\n\nTanguy Dubroca discovered that the netfilter subsystem in the Linux kernel\ndid not properly handle certain pointer data type, leading to an out-of-\nbounds write vulnerability. A privileged attacker could use this to cause a\ndenial of service (system crash) or possibly execute arbitrary code.\n(CVE-2023-35001)\n\n",null,[],[],[],[14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58,60],{"_key":15},"CVE-2023-0458",{"_key":17},"CVE-2023-1611",{"_key":19},"CVE-2023-2124",{"_key":21},"CVE-2023-2162",{"_key":23},"CVE-2023-2513",{"_key":25},"CVE-2023-3090",{"_key":27},"CVE-2023-3141",{"_key":29},"CVE-2023-3159",{"_key":31},"CVE-2023-3161",{"_key":33},"CVE-2023-3268",{"_key":35},"CVE-2023-3390",{"_key":37},"CVE-2023-35001",{"_key":39},"UBUNTU-CVE-2023-0458",{"_key":41},"UBUNTU-CVE-2023-1611",{"_key":43},"UBUNTU-CVE-2023-2124",{"_key":45},"UBUNTU-CVE-2023-2162",{"_key":47},"UBUNTU-CVE-2023-2513",{"_key":49},"UBUNTU-CVE-2023-3090",{"_key":51},"UBUNTU-CVE-2023-3141",{"_key":53},"UBUNTU-CVE-2023-3159",{"_key":55},"UBUNTU-CVE-2023-3161",{"_key":57},"UBUNTU-CVE-2023-3268",{"_key":59},"UBUNTU-CVE-2023-3390",{"_key":61},"UBUNTU-CVE-2023-35001",[],[],[65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88],{"_key":39},{"_key":41},{"_key":43},{"_key":45},{"_key":47},{"_key":49},{"_key":51},{"_key":53},{"_key":55},{"_key":57},{"_key":59},{"_key":61},{"_key":15},{"_key":17},{"_key":19},{"_key":21},{"_key":23},{"_key":25},{"_key":27},{"_key":29},{"_key":31},{"_key":33},{"_key":37},{"_key":35},"2023-07-26T15:54:27Z","2026-06-29T13:50:56.336516765Z",{"cisa_kev":92,"cisa_ransomware":92,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[94,100,105,109,113,117,121,125,129,133,137,141,145],{"url":95,"sources":96,"tags":98},"https://ubuntu.com/security/notices/USN-6254-1",[97],"osv_ubuntu",[99],"Advisory",{"url":101,"sources":102,"tags":103},"https://ubuntu.com/security/CVE-2023-0458",[97],[104],"REPORT",{"url":106,"sources":107,"tags":108},"https://ubuntu.com/security/CVE-2023-1611",[97],[104],{"url":110,"sources":111,"tags":112},"https://ubuntu.com/security/CVE-2023-2124",[97],[104],{"url":114,"sources":115,"tags":116},"https://ubuntu.com/security/CVE-2023-2162",[97],[104],{"url":118,"sources":119,"tags":120},"https://ubuntu.com/security/CVE-2023-2513",[97],[104],{"url":122,"sources":123,"tags":124},"https://ubuntu.com/security/CVE-2023-3090",[97],[104],{"url":126,"sources":127,"tags":128},"https://ubuntu.com/security/CVE-2023-3141",[97],[104],{"url":130,"sources":131,"tags":132},"https://ubuntu.com/security/CVE-2023-3159",[97],[104],{"url":134,"sources":135,"tags":136},"https://ubuntu.com/security/CVE-2023-3161",[97],[104],{"url":138,"sources":139,"tags":140},"https://ubuntu.com/security/CVE-2023-3268",[97],[104],{"url":142,"sources":143,"tags":144},"https://ubuntu.com/security/CVE-2023-3390",[97],[104],{"url":146,"sources":147,"tags":148},"https://ubuntu.com/security/CVE-2023-35001",[97],[104],[],[],[],[153,165,175,181],{"ecosystem":154,"name":155,"vendor":156,"product":155,"cpe_part":9,"purl_type":157,"purl_namespace":156,"purl_name":155,"source":9,"versions":158},"Ubuntu","linux","ubuntu","deb",[159],{"version":160,"is_range":161,"range_type":162,"version_start":9,"version_start_type":9,"version_end":163,"version_end_type":164,"fixed_in":9},"lt4_4_0_243_277",true,"ecosystem","4.4.0-243.277","excluding",{"ecosystem":154,"name":166,"vendor":156,"product":166,"cpe_part":9,"purl_type":157,"purl_namespace":156,"purl_name":166,"source":9,"versions":167},"linux-aws",[168,171,172],{"version":169,"is_range":161,"range_type":162,"version_start":9,"version_start_type":9,"version_end":170,"version_end_type":164,"fixed_in":9},"lt4_4_0_1121_127","4.4.0-1121.127",{"version":169,"is_range":161,"range_type":162,"version_start":9,"version_start_type":9,"version_end":170,"version_end_type":164,"fixed_in":9},{"version":173,"is_range":161,"range_type":162,"version_start":9,"version_start_type":9,"version_end":174,"version_end_type":164,"fixed_in":9},"lt4_4_0_1159_174","4.4.0-1159.174",{"ecosystem":154,"name":176,"vendor":156,"product":176,"cpe_part":9,"purl_type":157,"purl_namespace":156,"purl_name":176,"source":9,"versions":177},"linux-kvm",[178],{"version":179,"is_range":161,"range_type":162,"version_start":9,"version_start_type":9,"version_end":180,"version_end_type":164,"fixed_in":9},"lt4_4_0_1122_132","4.4.0-1122.132",{"ecosystem":154,"name":182,"vendor":156,"product":182,"cpe_part":9,"purl_type":157,"purl_namespace":156,"purl_name":182,"source":9,"versions":183},"linux-lts-xenial",[184,187],{"version":185,"is_range":161,"range_type":162,"version_start":9,"version_start_type":9,"version_end":186,"version_end_type":164,"fixed_in":9},"lt4_4_0_243_277~14_04_1","4.4.0-243.277~14.04.1",{"version":185,"is_range":161,"range_type":162,"version_start":9,"version_start_type":9,"version_end":186,"version_end_type":164,"fixed_in":9}]
