Infinite loop in Wireshark - CVE-2026-15163

Vulnerability identifier: #VU137182

CSH Severity: Medium

CVSS v4: 6.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-15163

CWE-ID: CWE-835

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to an infinite loop in the MIH, MPEG DSM-CC, eDonkey, and MEGACO protocol dissectors when parsing malformed packets or crafted packet trace files. A remote attacker can inject a malformed packet onto the wire or convince a victim to open a malformed packet trace file to cause a denial of service.

User interaction is required when exploitation uses a crafted packet trace file.
