If you cannot patch yet, avoid processing untrusted TTL files with affected versions of Wireshark to mitigate the risk of denial of service.

Description

CVE-2026-95386 is a medium severity vulnerability in Wireshark versions 4.6.0 through 4.6.8. It involves an infinite loop in the TTL file parser due to a loop with an unreachable exit condition, which can cause a denial of service (DoS) condition. The vulnerability does not impact confidentiality or integrity but affects availability by potentially causing the application to hang or become unresponsive.
