A local attacker could\npossibly use this to cause a denial of service (system crash).\n(CVE-2023-37453)\n\nLucas Leong discovered that the netfilter subsystem in the Linux kernel did\nnot properly validate some attributes passed from userspace. A local\nattacker could use this to cause a denial of service (system crash) or\npossibly expose sensitive information (kernel memory). (CVE-2023-39189)\n\nSunjoo Park discovered that the netfilter subsystem in the Linux kernel did\nnot properly validate u32 packets content, leading to an out-of-bounds read\nvulnerability. A local attacker could use this to cause a denial of service\n(system crash) or possibly expose sensitive information. (CVE-2023-39192)\n\nLucas Leong discovered that the netfilter subsystem in the Linux kernel did\nnot properly validate SCTP data, leading to an out-of-bounds read\nvulnerability. A local attacker could use this to cause a denial of service\n(system crash) or possibly expose sensitive information. (CVE-2023-39193)\n\nKyle Zeng discovered that the IPv4 implementation in the Linux kernel did\nnot properly handle socket buffers (skb) when performing IP routing in\ncertain circumstances, leading to a null pointer dereference vulnerability.\nA privileged attacker could use this to cause a denial of service (system\ncrash). (CVE-2023-42754)\n\nJason Wang discovered that the virtio ring implementation in the Linux\nkernel did not properly handle iov buffers in some situations. A local\nattacker in a guest VM could use this to cause a denial of service (host\nsystem crash). (CVE-2023-5158)\n\nAlon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel\ndid not properly handle queue initialization failures in certain\nsituations, leading to a use-after-free vulnerability. A remote attacker\ncould use this to cause a denial of service (system crash) or possibly\nexecute arbitrary code. (CVE-2023-5178)\n\nBudimir Markovic discovered that the perf subsystem in the Linux kernel did\nnot properly handle event groups, leading to an out-of-bounds write\nvulnerability. A local attacker could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code. (CVE-2023-5717)\n\nIt was discovered that the CIFS network file system implementation in the\nLinux kernel did not properly validate the server frame size in certain\nsituation, leading to an out-of-bounds read vulnerability. An attacker\ncould use this to construct a malicious CIFS image that, when operated on,\ncould cause a denial of service (system crash) or possibly expose sensitive\ninformation. (CVE-2023-6606)\n\nXingyuan Mo discovered that the netfilter subsystem in the Linux kernel did\nnot properly handle inactive elements in its PIPAPO data structure, leading\nto a use-after-free vulnerability. A local attacker could use this to cause\na denial of service (system crash) or possibly execute arbitrary code.\n(CVE-2023-6817)\n\nBudimir Markovic, Lucas De Marchi, and Pengfei Xu discovered that the perf\nsubsystem in the Linux kernel did not properly validate all event sizes\nwhen attaching new events, leading to an out-of-bounds write vulnerability.\nA local attacker could use this to cause a denial of service (system crash)\nor possibly execute arbitrary code. (CVE-2023-6931)\n\nIt was discovered that the IGMP protocol implementation in the Linux kernel\ncontained a race condition, 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-2023-6932)\n\nKevin Rich discovered that the netfilter subsystem in the Linux kernel did\nnot properly check deactivated elements in certain situations, leading to a\nuse-after-free vulnerability. A local attacker could use this to cause a\ndenial of service (system crash) or possibly execute arbitrary code.\n(CVE-2024-0193)","dates":{"published":"2024-02-14T08:17:09.000Z","modified":"2026-06-03T13:34:39.107Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"ubuntu","product":"linux-gcp-6.2","name":"linux-gcp-6.2","label":"linux-gcp-6.2","ecosystem":"Ubuntu","cpePart":null,"purl":"pkg:deb/ubuntu/linux-gcp-6.2","purlType":"deb","versions":[{"text":"< 6.2.0-1021.23~22.04.1","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 6.2.0-1021.23~22.04.1","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://ubuntu.com/security/notices/USN-6635-1","label":"ubuntu.com/security/notices/USN-6635-1","hostname":"ubuntu.com","tags":["Advisory"]},{"url":"https://ubuntu.com/security/CVE-2023-5158","label":"ubuntu.com/security/CVE-2023-5158","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2023-5178","label":"ubuntu.com/security/CVE-2023-5178","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2023-5717","label":"ubuntu.com/security/CVE-2023-5717","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2023-6606","label":"ubuntu.com/security/CVE-2023-6606","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2023-6817","label":"ubuntu.com/security/CVE-2023-6817","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2023-6931","label":"ubuntu.com/security/CVE-2023-6931","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2023-6932","label":"ubuntu.com/security/CVE-2023-6932","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2023-37453","label":"ubuntu.com/security/CVE-2023-37453","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2023-39189","label":"ubuntu.com/security/CVE-2023-39189","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2023-39192","label":"ubuntu.com/security/CVE-2023-39192","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2023-39193","label":"ubuntu.com/security/CVE-2023-39193","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2023-42754","label":"ubuntu.com/security/CVE-2023-42754","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2024-0193","label":"ubuntu.com/security/CVE-2024-0193","hostname":"ubuntu.com","tags":["REPORT"]}],"lineage":{"upstream":["CVE-2023-37453","CVE-2023-39189","CVE-2023-39192","CVE-2023-39193","CVE-2023-42754","CVE-2023-5158","CVE-2023-5178","CVE-2023-5717","CVE-2023-6606","CVE-2023-6817","CVE-2023-6931","CVE-2023-6932","CVE-2024-0193"],"downstream":[],"duplicates":[],"related":["CVE-2023-37453","CVE-2023-39189","CVE-2023-39192","CVE-2023-39193","CVE-2023-42754","CVE-2023-5158","CVE-2023-5178","CVE-2023-5717","CVE-2023-6606","CVE-2023-6817","CVE-2023-6931","CVE-2023-6932","CVE-2024-0193"]},"timeline":[{"kind":"published","date":"2024-02-14T08:17:09.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-06-03T13:34:39.107Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":0,"level":"minimal","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-20T22:50:52.296Z","stale":false,"partial":false}}
