CVE-2026-34620: Out-of-bounds Write (CWE-787) in Adobe Adobe DNG Software Development Kit (SDK)

CVE-2026-34620 is an out-of-bounds write vulnerability (CWE-787) in Adobe DNG SDK versions 1.7.1 2502 and earlier. This vulnerability allows an attacker to corrupt memory by writing outside the bounds of allocated memory, which can cause the affected application to crash or become unresponsive. Exploitation requires that a victim open a crafted malicious file, making user interaction necessary. No known exploits are reported in the wild, and no official remediation or patch has been disclosed at this time.

Successful exploitation leads to application denial-of-service by causing memory corruption and crashes. There is no indication of confidentiality or integrity impact. The attack vector requires local user interaction, limiting remote exploitation potential.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, users should avoid opening untrusted or suspicious files with affected versions of the Adobe DNG SDK. Monitor Adobe's official channels for updates and apply any released fixes promptly.
