{"id":"USN-6248-1","summary":"linux-oem-6.0 vulnerabilities","details":"It was discovered that the network queuing discipline implementation in the\nLinux kernel contained a null pointer dereference in some situations. A\nlocal attacker could use this to cause a denial of service (system crash).\n(CVE-2022-47929)\n\nIt was discovered that a race condition existed in Adreno GPU DRM driver in\nthe Linux kernel, leading to a double-free vulnerability. A local attacker\ncould use this to cause a denial of service (system crash).\n(CVE-2023-21106)\n\nStonejiajia, Shir Tamari and Sagi Tzadik discovered that the OverlayFS\nimplementation in the Ubuntu Linux kernel did not properly perform\npermission checks in certain situations. A local attacker could possibly\nuse this to gain elevated privileges. (CVE-2023-2640)\n\nMingi Cho discovered that the netfilter subsystem in the Linux kernel did\nnot properly validate the status of a nft chain while performing a lookup\nby id, leading to a use-after-free vulnerability. An attacker could use\nthis to cause a denial of service (system crash) or possibly execute\narbitrary code. (CVE-2023-31248)\n\nShir Tamari and Sagi Tzadik discovered that the OverlayFS implementation in\nthe Ubuntu Linux kernel did not properly perform permission checks in\ncertain situations. A local attacker could possibly use this to gain\nelevated privileges. (CVE-2023-32629)\n\nQuerijn Voet discovered that a race condition existed in the io_uring\nsubsystem in the Linux kernel, leading to a use-after-free vulnerability. A\nlocal attacker could use this to cause a denial of service (system crash)\nor possibly execute arbitrary code. (CVE-2023-3389)\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","modified":"2026-04-27T17:02:15.429708061Z","published":"2023-07-25T21:55:57Z","related":["UBUNTU-CVE-2022-47929","UBUNTU-CVE-2023-21106","UBUNTU-CVE-2023-2640","UBUNTU-CVE-2023-31248","UBUNTU-CVE-2023-32629","UBUNTU-CVE-2023-3389","UBUNTU-CVE-2023-35001"],"upstream":["CVE-2022-47929","CVE-2023-21106","CVE-2023-2640","CVE-2023-31248","CVE-2023-32629","CVE-2023-3389","CVE-2023-35001","UBUNTU-CVE-2022-47929","UBUNTU-CVE-2023-21106","UBUNTU-CVE-2023-2640","UBUNTU-CVE-2023-31248","UBUNTU-CVE-2023-32629","UBUNTU-CVE-2023-3389","UBUNTU-CVE-2023-35001"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6248-1"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-47929"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-2640"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-3389"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-21106"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-31248"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-32629"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-35001"}],"affected":[{"package":{"name":"linux-oem-6.0","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/linux-oem-6.0@6.0.0-1020.20?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.0-1020.20"}]}],"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","6.0.0-1017.17","6.0.0-1018.18","6.0.0-1019.19"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"6.0.0-1020.20","binary_name":"linux-buildinfo-6.0.0-1020-oem"},{"binary_version":"6.0.0-1020.20","binary_name":"linux-headers-6.0.0-1020-oem"},{"binary_version":"6.0.0-1020.20","binary_name":"linux-image-unsigned-6.0.0-1020-oem"},{"binary_version":"6.0.0-1020.20","binary_name":"linux-modules-6.0.0-1020-oem"},{"binary_version":"6.0.0-1020.20","binary_name":"linux-modules-ipu6-6.0.0-1020-oem"},{"binary_version":"6.0.0-1020.20","binary_name":"linux-modules-ivsc-6.0.0-1020-oem"},{"binary_version":"6.0.0-1020.20","binary_name":"linux-modules-iwlwifi-6.0.0-1020-oem"},{"binary_version":"6.0.0-1020.20","binary_name":"linux-oem-6.0-headers-6.0.0-1020"},{"binary_version":"6.0.0-1020.20","binary_name":"linux-oem-6.0-tools-6.0.0-1020"},{"binary_version":"6.0.0-1020.20","binary_name":"linux-oem-6.0-tools-host"},{"binary_version":"6.0.0-1020.20","binary_name":"linux-tools-6.0.0-1020-oem"}]},"database_specific":{"cves_map":{"cves":[{"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":"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-2022-47929"},{"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":"high","type":"Ubuntu"}],"id":"CVE-2023-2640"},{"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":"high","type":"Ubuntu"}],"id":"CVE-2023-3389"},{"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":"high","type":"Ubuntu"}],"id":"CVE-2023-21106"},{"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":"high","type":"Ubuntu"}],"id":"CVE-2023-31248"},{"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":"high","type":"Ubuntu"}],"id":"CVE-2023-32629"},{"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":"high","type":"Ubuntu"}],"id":"CVE-2023-35001"}],"ecosystem":"Ubuntu:22.04:LTS"},"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/usn/USN-6248-1.json"}}],"schema_version":"1.7.5"}
