A local attacker\ncould use this to leak or alter data from other processes that use huge\npages. (CVE-2021-4002)\n\nIt was discovered that the eBPF implementation in the Linux kernel did\nnot properly validate the memory size of certain ring buffer operation\narguments. A local attacker could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code. (CVE-2021-4204)\n\nIt was discovered that a race condition existed in the overlay file system\nimplementation in the Linux kernel. A local attacker could use this to\ncause a denial of service (system crash). (CVE-2021-20321)\n\nIt was discovered that the NFC subsystem in the Linux kernel contained a\nuse-after-free vulnerability in its NFC Controller Interface (NCI)\nimplementation. A local attacker could possibly use this to cause a denial\nof service (system crash) or execute arbitrary code. (CVE-2021-3760)\n\nIt was discovered that an integer overflow could be triggered in the eBPF\nimplementation in the Linux kernel when preallocating objects for stack\nmaps. A privileged local attacker could use this to cause a denial of\nservice or possibly execute arbitrary code. (CVE-2021-41864)\n\nIt was discovered that the KVM implementation for POWER8 processors in the\nLinux kernel did not properly keep track if a wakeup event could be\nresolved by a guest. An attacker in a guest VM could possibly use this to\ncause a denial of service (host OS crash). (CVE-2021-43056)\n\nIt was discovered that the TIPC Protocol implementation in the Linux kernel\ndid not properly validate MSG_CRYPTO messages in some situations. An\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2021-43267)\n\nIt was discovered that the ISDN CAPI implementation in the Linux kernel\ncontained a race condition in certain situations that could trigger an\narray out-of-bounds bug. A privileged local attacker could possibly use\nthis to cause a denial of service or execute arbitrary code.\n(CVE-2021-43389)\n\n",null,[],[],[],[14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44],{"_key":15},"CVE-2021-20321",{"_key":17},"CVE-2021-3760",{"_key":19},"CVE-2021-4002",{"_key":21},"CVE-2021-41864",{"_key":23},"CVE-2021-4204",{"_key":25},"CVE-2021-43056",{"_key":27},"CVE-2021-43267",{"_key":29},"CVE-2021-43389",{"_key":31},"UBUNTU-CVE-2021-20321",{"_key":33},"UBUNTU-CVE-2021-3760",{"_key":35},"UBUNTU-CVE-2021-4002",{"_key":37},"UBUNTU-CVE-2021-41864",{"_key":39},"UBUNTU-CVE-2021-4204",{"_key":41},"UBUNTU-CVE-2021-43056",{"_key":43},"UBUNTU-CVE-2021-43267",{"_key":45},"UBUNTU-CVE-2021-43389",[],[],[49,50,51,52,53,54,55,56],{"_key":31},{"_key":33},{"_key":35},{"_key":37},{"_key":39},{"_key":41},{"_key":43},{"_key":45},"2022-01-11T04:58:00Z","2026-06-03T14:04:01.539545881Z",{"cisa_kev":60,"cisa_ransomware":60,"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,[62,68,73,77,81,85,89,93,97,101],{"url":63,"sources":64,"tags":66},"https://ubuntu.com/security/notices/USN-5218-1",[65],"osv_ubuntu",[67],"Advisory",{"url":69,"sources":70,"tags":71},"https://ubuntu.com/security/CVE-2021-3760",[65],[72],"REPORT",{"url":74,"sources":75,"tags":76},"https://ubuntu.com/security/CVE-2021-4002",[65],[72],{"url":78,"sources":79,"tags":80},"https://ubuntu.com/security/CVE-2021-4204",[65],[72],{"url":82,"sources":83,"tags":84},"https://ubuntu.com/security/CVE-2021-20321",[65],[72],{"url":86,"sources":87,"tags":88},"https://ubuntu.com/security/CVE-2021-41864",[65],[72],{"url":90,"sources":91,"tags":92},"https://ubuntu.com/security/CVE-2021-43056",[65],[72],{"url":94,"sources":95,"tags":96},"https://ubuntu.com/security/CVE-2021-43267",[65],[72],{"url":98,"sources":99,"tags":100},"https://ubuntu.com/security/CVE-2021-43389",[65],[72],{"url":102,"sources":103,"tags":104},"https://launchpad.net/bugs/1956585",[65],[72],[],[],[],[109],{"ecosystem":110,"name":111,"vendor":112,"product":111,"cpe_part":9,"purl_type":113,"purl_namespace":112,"purl_name":111,"source":9,"versions":114},"Ubuntu","linux-oem-5.13","ubuntu","deb",[115],{"version":116,"is_range":117,"range_type":118,"version_start":9,"version_start_type":9,"version_end":119,"version_end_type":120,"fixed_in":9},"lt5_13_0_1026_32",true,"ecosystem","5.13.0-1026.32","excluding"]
