{"id":"AZL-83021","summary":"CVE-2026-40333 affecting package libgphoto2 2.5.31-1","details":"libgphoto2 is a camera access and control library. In versions up to and including 2.5.33, two functions in camlibs/ptp2/ptp-pack.c accept a data pointer but no length parameter, performing unbounded reads. Their callers in ptp_unpack_EOS_events() have xsize available but never pass it, leaving both functions unable to validate reads against the actual buffer boundary. Commit 1817ecead20c2aafa7549dac9619fe38f47b2f53 patches the issue.","modified":"2026-09-20T05:32:18Z","published":"2026-04-18T00:16:37Z","upstream":["CVE-2026-40333"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40333"}],"affected":[{"package":{"name":"libgphoto2","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/libgphoto2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"2.5.31-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-83021.json"}}],"schema_version":"1.9.0"}
