CVE ID :CVE-2026-66360
Published : July 30, 2026, 11:16 p.m. | 1 hour, 36 minutes ago
Description :The ISO Presentation layer contains a flaw in the handling of specific parameters during normal mode negotiation. A missing length check in the processing of the encoded presentation data allows an attacker controlled field with a zero length value to trigger a bounded heap over read. This condition occurs before MMS session establishment, a crafted TCP/102 connection attempt can trigger the issue. The resulting over read causes the process to terminate, leading to a denial of service condition.
Severity: 8.7 | HIGH
