{"id":"USN-6123-1","summary":"linux-oem-6.0 vulnerabilities","details":"Patryk Sondej and Piotr Krysiuk discovered that a race condition existed in\nthe netfilter subsystem of the Linux kernel when processing batch requests,\nleading to a use-after-free vulnerability. A local attacker could use this\nto cause a denial of service (system crash) or possibly execute arbitrary\ncode. (CVE-2023-32233)\n\nReima Ishii discovered that the nested KVM implementation for Intel x86\nprocessors in the Linux kernel did not properly validate control registers\nin certain situations. An attacker in a guest VM could use this to cause a\ndenial of service (guest crash). (CVE-2023-30456)\n\nIt was discovered that the Xircom PCMCIA network device driver in the Linux\nkernel did not properly handle device removal events. A physically\nproximate attacker could use this to cause a denial of service (system\ncrash). (CVE-2023-1670)\n\nJean-Baptiste Cayrou discovered that the shiftfs file system in the Ubuntu\nLinux kernel contained a race condition when handling inode locking in some\nsituations. A local attacker could use this to cause a denial of service\n(kernel deadlock). (CVE-2023-2612)\n\nIt was discovered that the NTFS file system implementation in the Linux\nkernel did not properly handle a loop termination condition, leading to an\nout-of-bounds read vulnerability. A local attacker could use this to cause\na denial of service (system crash) or possibly expose sensitive\ninformation. (CVE-2023-26606)\n\n","modified":"2026-05-23T01:48:28.673919694Z","published":"2023-05-30T17:37:08Z","related":["UBUNTU-CVE-2023-1670","UBUNTU-CVE-2023-2612","UBUNTU-CVE-2023-26606","UBUNTU-CVE-2023-30456","UBUNTU-CVE-2023-32233"],"upstream":["CVE-2023-26606","UBUNTU-CVE-2023-26606"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6123-1"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-26606"}],"affected":[{"package":{"name":"linux-oem-6.0","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/linux-oem-6.0?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.0-1017.17"}]}],"versions":["6.0.0-1006.6","6.0.0-1007.7","6.0.0-1008.8","6.0.0-1009.9","6.0.0-1010.10","6.0.0-1011.11","6.0.0-1012.12","6.0.0-1013.13","6.0.0-1014.14","6.0.0-1015.15","6.0.0-1016.16"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"6.0.0-1017.17","binary_name":"linux-buildinfo-6.0.0-1017-oem"},{"binary_version":"6.0.0-1017.17","binary_name":"linux-headers-6.0.0-1017-oem"},{"binary_version":"6.0.0-1017.17","binary_name":"linux-image-unsigned-6.0.0-1017-oem"},{"binary_version":"6.0.0-1017.17","binary_name":"linux-modules-6.0.0-1017-oem"},{"binary_version":"6.0.0-1017.17","binary_name":"linux-modules-ipu6-6.0.0-1017-oem"},{"binary_version":"6.0.0-1017.17","binary_name":"linux-modules-ivsc-6.0.0-1017-oem"},{"binary_version":"6.0.0-1017.17","binary_name":"linux-modules-iwlwifi-6.0.0-1017-oem"},{"binary_version":"6.0.0-1017.17","binary_name":"linux-oem-6.0-headers-6.0.0-1017"},{"binary_version":"6.0.0-1017.17","binary_name":"linux-oem-6.0-tools-6.0.0-1017"},{"binary_version":"6.0.0-1017.17","binary_name":"linux-oem-6.0-tools-host"},{"binary_version":"6.0.0-1017.17","binary_name":"linux-tools-6.0.0-1017-oem"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/usn/USN-6123-1.json","cves_map":{"ecosystem":"Ubuntu:22.04:LTS","cves":[{"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":"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-2023-26606"}]}}}],"schema_version":"1.7.5"}
