A local host OS user can exploit this to cause a denial of\nservice (kill arbitrary processes, or system disruption) by leveraging\n/dev/kvm access. (CVE-2014-3690)\n\nDon Bailey discovered a flaw in the LZO decompress algorithm used by the\nLinux kernel. An attacker could exploit this flaw to cause a denial of\nservice (memory corruption or OOPS). (CVE-2014-4608)\n\nAndy Lutomirski discovered a flaw in how the Linux kernel handles\npivot_root when used with a chroot directory. A local user could exploit\nthis flaw to cause a denial of service (mount-tree loop). (CVE-2014-7970)\n\nAndy Lutomirski discovered that the Linux kernel was not checking the\nCAP_SYS_ADMIN when remounting filesystems to read-only. A local user could\nexploit this flaw to cause a denial of service (loss of writability).\n(CVE-2014-7975)\n",null,[],[],[],[14,16,18,20,22,24,26,28],{"_key":15},"CVE-2014-3690",{"_key":17},"CVE-2014-4608",{"_key":19},"CVE-2014-7970",{"_key":21},"CVE-2014-7975",{"_key":23},"UBUNTU-CVE-2014-3690",{"_key":25},"UBUNTU-CVE-2014-4608",{"_key":27},"UBUNTU-CVE-2014-7970",{"_key":29},"UBUNTU-CVE-2014-7975",[],[],[33,34,35,36],{"_key":25},{"_key":23},{"_key":27},{"_key":29},"2014-11-25T04:08:18Z","2026-04-22T09:04:13.235892Z",{"cisa_kev":40,"cisa_ransomware":40,"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,[42,48,53,57,61],{"url":43,"sources":44,"tags":46},"https://ubuntu.com/security/notices/USN-2420-1",[45],"osv_ubuntu",[47],"Advisory",{"url":49,"sources":50,"tags":51},"https://ubuntu.com/security/CVE-2014-3690",[45],[52],"REPORT",{"url":54,"sources":55,"tags":56},"https://ubuntu.com/security/CVE-2014-4608",[45],[52],{"url":58,"sources":59,"tags":60},"https://ubuntu.com/security/CVE-2014-7970",[45],[52],{"url":62,"sources":63,"tags":64},"https://ubuntu.com/security/CVE-2014-7975",[45],[52],[],[],[],[69],{"ecosystem":70,"name":71,"vendor":72,"product":71,"cpe_part":9,"purl_type":73,"purl_namespace":72,"purl_name":71,"source":9,"versions":74},"Ubuntu","linux","ubuntu","deb",[75],{"version":76,"is_range":77,"range_type":78,"version_start":9,"version_start_type":9,"version_end":79,"version_end_type":80,"fixed_in":9},"lt3_13_0_40_69",true,"ecosystem","3.13.0-40.69","excluding"]
