Vulnerability from fkie_nvd - Published: 2016-05-23 10:59 - Updated: 2026-06-17 00:48
Summary
The tipc_nl_publ_dump function in net/tipc/socket.c in the Linux kernel through 4.6 does not verify socket existence, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a dumpit operation.
