CVE-2026-76880Source published Source updated
RRC protocol dissector crash in 4.6.0 to 4.6.7 and 4.4.0 to 4.4.18 allows denial of service A flaw was found in Wireshark. This vulnerability allows a remote attacker to cause a denial of service (DoS) by sending a specially crafted Universal Mobile Telecommunications System (UMTS) RRC protocol packet. The flaw resides in the UMTS RRC protocol dissector, which can lead to a crash of the Wireshark application. This can disrupt network analysis operations. While exploitable by a remote attacker, successful exploitation requires a user to either open a malicious capture file or actively capture network traffic containing the crafted packet. This limits the attack surface to scenarios where Wireshark is actively used for network analysis. Red Hat severity: Moderate — CVSS 5.5…
