CVE-2026-76923 [MEDIUM] CWE-125 wireshark: Wireshark: Denial of Service due to out-of-bounds read in Bluetooth HFP dissector
wireshark: Wireshark: Denial of Service due to out-of-bounds read in Bluetooth HFP dissector
A flaw was found in Wireshark. An out-of-bounds read vulnerability exists within the Bluetooth HFP (Hands-Free Profile) protocol dissector. A remote attacker could exploit this by tricking a user into opening a specially crafted capture file. Successful exploitation leads to a crash of the Wireshark application, resulting in a denial of service.
Statement: An out-of-bounds read was found in the Bluetooth HFP protocol dissector in Wireshark versions 4.4.0 through 4.4.18 and 4.6.0 through 4.6.7. Red Hat Enterprise Linux 6, 7, 8, and 9 ship Wireshark versions prior to the affected range and are not vulnerable. Red Hat Enterprise Linux 10 and Red Hat In-Vehicle OS ship an affected version of Wireshar
