{"id":"AZL-89058","summary":"CVE-2026-46234 affecting package kernel for versions less than 6.6.141.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nvsock: fix buffer size clamping order\n\nIn vsock_update_buffer_size(), the buffer size was being clamped to the\nmaximum first, and then to the minimum. If a user sets a minimum buffer\nsize larger than the maximum, the minimum check overrides the maximum\ncheck, inverting the constraint.\n\nThis breaks the intended socket memory boundaries by allowing the\nvsk-\u003ebuffer_size to grow beyond the configured vsk-\u003ebuffer_max_size.\n\nFix this by checking the minimum first, and then the maximum. This\nensures the buffer size never exceeds the buffer_max_size.","modified":"2026-08-28T17:47:53.023302814Z","published":"2026-05-28T10:16:39Z","upstream":["CVE-2026-46234"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46234"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.141.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-89058.json"}}],"schema_version":"1.9.0"}
