Description
A heap-based buffer overflow in VPN certificate ASN.1 decoding may allow an unauthenticated remote attacker to execute arbitrary code on Check Point Quantum Security Management and Quantum Security Gateway systems.
Exploited in the wild (ENISA)
Only ENISA's EU KEV lists it. Across the site, “known exploited” (the KEV badge, the filter, the feeds and exports) means CISA's KEV, so it does not count as one there.
ENISA's EU Vulnerability Database lists it as exploited, from ENISA's EU KEV, since 25 Sept 2026.
