{"id":"AZL-103073","summary":"CVE-2026-81869 affecting package cri-o 1.30.1-1","details":"OpenTelemetry-Go is the Go implementation of OpenTelemetry. From version 1.10.0 until 1.33.0, the sdk/trace/span.go attribute truncation path can fail to enforce AttributeValueLengthLimit for string and string-slice attributes containing the valid Unicode replacement character U+FFFD. safeTruncateValidUTF8 treats the valid replacement rune as invalid UTF-8 and returns the original input, while strings.ToValidUTF8 leaves that valid rune unchanged, so a second safeTruncate attempt can also return the oversized value. An attacker who controls span attribute content can retain values longer than the configured limit, increasing per-span memory use and weakening denial-of-service protection in the instrumented process. This issue is fixed in version 1.33.0.","modified":"2026-09-21T05:37:51Z","published":"2026-09-16T21:17:22Z","upstream":["CVE-2026-81869"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-81869"}],"affected":[{"package":{"name":"cri-o","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/cri-o"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.30.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-103073.json"}}],"schema_version":"1.9.0"}
