CVE-2022-0583Public exploitNetwork attack vector

Application crash via premature PVFS pointer dereference

Published Feb 14, 2022 · Updated Nov 3, 2025

Out-of-bounds read in Wireshark Foundation Wireshark 3.6.0 through 3.6.1 and 3.4.0 through 3.4.11 allows attackers to crash the application. In dissect_pvfs2_getconfig_response, the inner loop dereferences a configuration-line pointer before verifying that processed bytes remain within the packet buffer. Reachability requires a malformed PVFS packet injected onto a monitored network or a user opening a crafted capture file, and the reported consequence is a one-byte heap over-read followed by a process crash.
