SUSE CVE-2026-40333

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 ptpunpackEOSevents have xsize available but never pass it, leaving both...

SUSE CVE-2026-40335

libgphoto2 is a camera access and control library. Versions up to and including 2.5.33 have an out-of-bounds read in ptpunpackDPV 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 li...

SUSE CVE-2026-40336

libgphoto2 is a camera access and control library. Versions up to and including 2.5.33 have a memory leak in ptpunpackSonyDPD in camlibs/ptp2/ptp-pack.c lines 884-885. When processing a secondary enumeration list introduced in 2024+ Sony cameras, the function overwrites dpd-FORM.Enum.SupportedVal...
