{"id":"USN-5165-1","summary":"linux-oem-5.14 vulnerabilities","details":"It 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 the SCTP protocol implementation in the Linux kernel\ndid not properly verify VTAGs in some situations. A remote attacker could\npossibly use this to cause a denial of service (connection disassociation).\n(CVE-2021-3772)\n\nIt was discovered that the AMD Radeon GPU driver in the Linux kernel did\nnot properly validate writes in the debugfs file system. A privileged\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2021-42327)\n\nLuo Likang discovered that the FireDTV Firewire driver in the Linux kernel\ndid not properly perform bounds checking in some situations. A local\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2021-42739)\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","modified":"2026-02-10T04:42:24Z","published":"2021-11-30T23:48:03Z","related":["UBUNTU-CVE-2021-3760","UBUNTU-CVE-2021-3772","UBUNTU-CVE-2021-42327","UBUNTU-CVE-2021-42739","UBUNTU-CVE-2021-43056","UBUNTU-CVE-2021-43267","UBUNTU-CVE-2021-43389"],"upstream":["CVE-2021-3760","CVE-2021-3772","CVE-2021-42327","CVE-2021-42739","CVE-2021-43056","CVE-2021-43267","CVE-2021-43389","UBUNTU-CVE-2021-3760","UBUNTU-CVE-2021-3772","UBUNTU-CVE-2021-42327","UBUNTU-CVE-2021-42739","UBUNTU-CVE-2021-43056","UBUNTU-CVE-2021-43267","UBUNTU-CVE-2021-43389"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-5165-1"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2021-3760"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2021-3772"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2021-42327"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2021-42739"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2021-43056"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2021-43267"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2021-43389"}],"affected":[{"package":{"name":"linux-oem-5.14","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/linux-oem-5.14@5.14.0-1008.8?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.14.0-1008.8"}]}],"versions":["5.14.0-1004.4","5.14.0-1005.5","5.14.0-1007.7"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"linux-buildinfo-5.14.0-1008-oem","binary_version":"5.14.0-1008.8"},{"binary_name":"linux-headers-5.14.0-1008-oem","binary_version":"5.14.0-1008.8"},{"binary_name":"linux-image-unsigned-5.14.0-1008-oem","binary_version":"5.14.0-1008.8"},{"binary_name":"linux-modules-5.14.0-1008-oem","binary_version":"5.14.0-1008.8"},{"binary_name":"linux-oem-5.14-headers-5.14.0-1008","binary_version":"5.14.0-1008.8"},{"binary_name":"linux-oem-5.14-tools-5.14.0-1008","binary_version":"5.14.0-1008.8"},{"binary_name":"linux-oem-5.14-tools-host","binary_version":"5.14.0-1008.8"},{"binary_name":"linux-tools-5.14.0-1008-oem","binary_version":"5.14.0-1008.8"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/usn/USN-5165-1.json","cves_map":{"ecosystem":"Ubuntu:20.04:LTS","cves":[{"id":"CVE-2021-3760","severity":[{"score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","type":"CVSS_V3"},{"score":"medium","type":"Ubuntu"}]},{"id":"CVE-2021-3772","severity":[{"score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H","type":"CVSS_V3"},{"score":"low","type":"Ubuntu"}]},{"id":"CVE-2021-42327","severity":[{"score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","type":"CVSS_V3"},{"score":"low","type":"Ubuntu"}]},{"id":"CVE-2021-42739","severity":[{"score":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","type":"CVSS_V3"},{"score":"medium","type":"Ubuntu"}]},{"id":"CVE-2021-43056","severity":[{"score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","type":"CVSS_V3"},{"score":"medium","type":"Ubuntu"}]},{"id":"CVE-2021-43267","severity":[{"score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","type":"CVSS_V3"},{"score":"medium","type":"Ubuntu"}]},{"id":"CVE-2021-43389","severity":[{"score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","type":"CVSS_V3"},{"score":"low","type":"Ubuntu"}]}]}}}],"schema_version":"1.7.3"}
