A specially crafted EXR file containing an unknown-type attribute with dataSize set to zero causes the parser to create an opaque attribute with a NULL packed_data pointer. The OpaqueAttribute constructor passes the NULL pointer to memcpy() without validating the zero-size condition, resulting in undefined behavior and process termination, leading to denial of service.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 9 · no fix planned: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 9 · updated 2026-09-24 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-88384.json)","depth":"twilight","depthScore":42,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":210327,"id":"CVE-2026-88384","ts":1790275824464,"field":"exploit_available","old":"false","new":"true"},{"seq":210326,"id":"CVE-2026-88384","ts":1790275824464,"field":"cvss","old":null,"new":"5.5"},{"seq":210325,"id":"CVE-2026-88384","ts":1790275824464,"field":"severity","old":"none","new":"medium"}]}
