{"id":"AZL-112238","summary":"CVE-2026-78661 affecting package sriov-network-device-plugin 3.7.0-9","details":"When coalescing adjacent text nodes in addText and fosterParent, appending to an existing TextNode's Data via string concatenation (n.Data += text) reallocated and copied the accumulated string on every token. Inputs containing many short text runs separated by ignored end tags (such as \"a\u003c/x\u003e\") caused O(n^2) allocations and byte copies. Accumulate coalesced text in per-node byte slices during parsing and materialize Data strings once at the end of parse.","modified":"2026-11-01T14:17:38.511423542Z","published":"2026-10-27T22:18:05Z","upstream":["CVE-2026-78661"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-78661"}],"affected":[{"package":{"name":"sriov-network-device-plugin","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/sriov-network-device-plugin"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"3.7.0-9"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-112238.json"}}],"schema_version":"1.9.2"}
