CVE-2026-0962: Out-of-bounds Write in Wireshark
Noroxi assessment
Priority: Monitor (action score 26/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.25% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
- Fixed version: Wireshark Foundation Wireshark 4.4.13, 4.6.3.
Low priority for now. Upgrade to Wireshark Foundation Wireshark 4.4.13, 4.6.3 or later.
