An\nattacker could use this to construct a malicious ext4 file system image\nthat, when mounted, could cause a denial of service (system crash).\n(CVE-2021-33631)\n\nIt was discovered that the ATA over Ethernet (AoE) driver in the Linux\nkernel contained a race condition, leading to a use-after-free\nvulnerability. An attacker could use this to cause a denial of service or\npossibly execute arbitrary code. (CVE-2023-6270)\n\nSander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida\ndiscovered that the Linux kernel mitigations for the initial Branch History\nInjection vulnerability (CVE-2022-0001) were insufficient for Intel\nprocessors. A local attacker could potentially use this to expose sensitive\ninformation. (CVE-2024-2201)\n\nGui-Dong Han discovered that the software RAID driver in the Linux kernel\ncontained a race condition, leading to an integer overflow vulnerability. A\nprivileged attacker could possibly use this to cause a denial of service\n(system crash). (CVE-2024-23307)\n\nBai Jiaju discovered that the Xceive XC4000 silicon tuner device driver in\nthe Linux kernel contained a race condition, leading to an integer overflow\nvulnerability. An attacker could possibly use this to cause a denial of\nservice (system crash). (CVE-2024-24861)\n\nSeveral security issues were discovered in the Linux kernel.\nAn attacker could possibly use these to compromise the system.\nThis update corrects flaws in the following subsystems:\n  - Block layer subsystem;\n  - Hardware random number generator core;\n  - GPU drivers;\n  - AFS file system;\n  - Memory management;\n  - Netfilter;\n(CVE-2024-26642, CVE-2024-26922, CVE-2024-26720, CVE-2024-26736,\nCVE-2024-26898, CVE-2021-47063, CVE-2023-52615)","dates":{"published":"2024-07-04T19:11:24.000Z","modified":"2026-08-06T03:04:16.099Z","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-azure","name":"linux-azure","label":"linux-azure","ecosystem":"Ubuntu","cpePart":null,"purl":"pkg:deb/ubuntu/linux-azure","purlType":"deb","versions":[{"text":"< 4.15.0-1178.193~16.04.1","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 4.15.0-1178.193~16.04.1","eol":null,"hubHref":null},{"vendor":"ubuntu","product":"linux-azure-4.15","name":"linux-azure-4.15","label":"linux-azure-4.15","ecosystem":"Ubuntu","cpePart":null,"purl":"pkg:deb/ubuntu/linux-azure-4.15","purlType":"deb","versions":[{"text":"< 4.15.0-1178.193","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 4.15.0-1178.193","eol":null,"hubHref":null}],"affectedCount":2,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://ubuntu.com/security/notices/USN-6866-2","label":"ubuntu.com/security/notices/USN-6866-2","hostname":"ubuntu.com","tags":["Advisory"]},{"url":"https://ubuntu.com/security/CVE-2021-33631","label":"ubuntu.com/security/CVE-2021-33631","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2021-47063","label":"ubuntu.com/security/CVE-2021-47063","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2023-6270","label":"ubuntu.com/security/CVE-2023-6270","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2023-52615","label":"ubuntu.com/security/CVE-2023-52615","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2024-2201","label":"ubuntu.com/security/CVE-2024-2201","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2024-23307","label":"ubuntu.com/security/CVE-2024-23307","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2024-24861","label":"ubuntu.com/security/CVE-2024-24861","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2024-26642","label":"ubuntu.com/security/CVE-2024-26642","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2024-26720","label":"ubuntu.com/security/CVE-2024-26720","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2024-26736","label":"ubuntu.com/security/CVE-2024-26736","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2024-26898","label":"ubuntu.com/security/CVE-2024-26898","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://ubuntu.com/security/CVE-2024-26922","label":"ubuntu.com/security/CVE-2024-26922","hostname":"ubuntu.com","tags":["REPORT"]}],"lineage":{"upstream":["CVE-2021-33631","CVE-2021-47063","CVE-2023-52615","CVE-2023-6270","CVE-2024-2201","CVE-2024-23307","CVE-2024-24861","CVE-2024-26642","CVE-2024-26720","CVE-2024-26736","CVE-2024-26898","CVE-2024-26922"],"downstream":[],"duplicates":[],"related":["CVE-2021-33631","CVE-2021-47063","CVE-2023-52615","CVE-2023-6270","CVE-2024-2201","CVE-2024-23307","CVE-2024-24861","CVE-2024-26642","CVE-2024-26720","CVE-2024-26736","CVE-2024-26898","CVE-2024-26922"]},"timeline":[{"kind":"published","date":"2024-07-04T19:11:24.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-08-06T03:04:16.099Z","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":"2026-10-19T15:44:53.485Z","stale":false,"partial":false}}
