This product adopts a rolling release strategy to maintain continuous delivery. Therefore, version details for affected or updated releases cannot be specified. The identifier of the patch is 007041bb2dd6d140c9e707caddfb0a49ecf96469. Applying a patch is the recommended action to fix this issue. This was reproducible with a minimal 55-byte PoC via the standard image-decode fuzz target but evidence for an actual exploitable defect is thin.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK
