CVE-2026-15163 [HIGH] CWE-835 wireshark: Wireshark: Denial of Service via multiple protocol dissector infinite loops
wireshark: Wireshark: Denial of Service via multiple protocol dissector infinite loops
Multiple protocol dissector infinite loops in Wireshark 4.6.0 to 4.6.6 and 4.4.0 to 4.4.16 allow denial of service
A flaw was found in Wireshark. A local user could trigger multiple protocol dissector infinite loops by providing specially crafted network traffic for analysis. This could lead to a Denial of Service (DoS) condition, making the application unresponsive.
Statement: This Moderate impact flaw in Wireshark allows a local attacker to trigger multiple protocol dissector infinite loops, leading to a denial of service. Exploitation requires a local user to open and analyze specially crafted network traffic, limiting the attack vector to interactive use cases rather than automated or remote explo
