{"id":"AZL-105170","summary":"CVE-2026-42784 affecting package kata-containers-cc 3.15.0.aks0-21","details":"A flaw was found in sequoia-openpgp. The library incorrectly infers key flags for older certificates when a key flags subpacket is missing, leading to a discrepancy in how key capabilities are viewed. This key flag confusion allows an attacker to bypass the back-signature check. Consequently, an attacker can illegitimately bind an arbitrary subkey to their own certificate and forge signatures, completely compromising cryptographic integrity.","modified":"2026-10-03T05:35:10Z","published":"2026-09-16T17:17:18Z","upstream":["CVE-2026-42784"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42784"}],"affected":[{"package":{"name":"kata-containers-cc","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kata-containers-cc"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"3.15.0.aks0-21"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-105170.json"}}],"schema_version":"1.9.0"}
