CVE-2026-99246 Nov 3, 2026 Source: Vendor
In the Linux kernel, the following vulnerability has been resolved:
tipc: protect node reset trace dump with node lock
The tipc_node_reset_links trace event asks tipc_node_dump() to walk the
node's link entries. Unlike the other node events that request link data,
this event runs without the node lock.
This permits bearer teardown to free a link while the trace callback is
dumping it:
