{"id":"AZL-83030","summary":"CVE-2026-40340 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 vulnerability in `ptp_unpack_OI()` in `camlibs/ptp2/ptp-pack.c` (lines 530–563). The function validates `len \u003c PTP_oi_SequenceNumber` (i.e., len \u003c 48) but subsequently accesses offsets 48–56, up to 9 bytes beyond the validated boundary, via the Samsung Galaxy 64-bit objectsize detection heuristic. Commit 7c7f515bc88c3d0c4098ac965d313518e0ccbe33 fixes the issue.","modified":"2026-08-31T05:26:07Z","published":"2026-04-18T00:16:38Z","upstream":["CVE-2026-40340"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40340"}],"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-83030.json"}}],"schema_version":"1.9.0"}
