Denial of Service via IEEE 802.11 protocol dissector crash

Summary

IEEE 802.11 protocol dissector crash in Wireshark 4.6.0 to 4.6.6 and 4.4.0 to 4.4.16 allows denial of service A flaw was found in Wireshark, a network protocol analyzer. An attacker could exploit this vulnerability by sending a specially crafted network packet, which would cause the IEEE 802.11 protocol dissector to crash. This issue results in a denial of service, making the Wireshark application unresponsive and unavailable to users. This Moderate impact flaw in Wireshark allows a denial of service when processing specially crafted IEEE 802.11 network packets. The vulnerability affects the availability of the Wireshark application, potentially disrupting network analysis operations, and requires an attacker to inject or present malicious 802.11 traffic to the system. Red Hat severity: Moderate — CVSS 5.7 (CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). Weakness: CWE-476. Affected Red Hat products: Red Hat Enterprise Linux 10.
