{"id":"AZL-83018","summary":"CVE-2026-40335 affecting package libgphoto2 2.5.31-1","details":"libgphoto2 is a camera access and control library. Versions up to and including 2.5.33 have an out-of-bounds read in `ptp_unpack_DPV()` in `camlibs/ptp2/ptp-pack.c` (lines 622–629). The UINT128 and INT128 cases advance `*offset += 16` without verifying that 16 bytes remain in the buffer. The entry check at line 609 only guarantees `*offset \u003c total` (at least 1 byte available), leaving up to 15 bytes unvalidated. Commit 433bde9888d70aa726e32744cd751d7dbe94379a patches the issue.","modified":"2026-08-30T05:24:52Z","published":"2026-04-18T00:16:37Z","upstream":["CVE-2026-40335"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40335"}],"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-83018.json"}}],"schema_version":"1.9.0"}
