{"id":"AZL-108876","summary":"CVE-2026-98453 affecting package kernel 6.6.157.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: client: close handle after create-context parsing failure\n\nSMB2_open() accounts a successful CREATE response as a remote open before\nparsing its create contexts.  If smb2_parse_contexts() rejects malformed\ncontext data, SMB2_open() returns without closing the handle, leaving the\nserver-side handle open and num_remote_opens elevated.\n\nClose the handle after a post-CREATE context parsing failure so the error\npath releases the remote resource and balances the open count.","modified":"2026-10-20T05:35:13Z","published":"2026-10-18T16:16:55Z","upstream":["CVE-2026-98453"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98453"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-108876.json"}}],"schema_version":"1.9.0"}
