CVE-2026-99246

A flaw was found in the Linux kernel's TIPC Transparent Inter-Process Communication subsystem. A race condition occurs when tracing link reset events without proper locking, which can cause link data to be freed while it is actively being accessed. An unauthenticated remote attacker could exploit...

CVE-2026-99246

In the Linux kernel, the following vulnerability has been resolved: tipc: protect node reset trace dump with node lock The tipcnoderesetlinks trace event asks tipcnodedump to walk the node's link entries. Unlike the other node events that request link data, this event runs without the node lock...

CVE-2026-99246

The Linux kernel contains a slab-use-after-free vulnerability in the tipc (Transparent Inter-Process Communication) component. The tipc_node_reset_links trace event calls tipc_node_dump() without acquiring the necessary node lock . This allows a concurrent bearer teardown to free a link via tipc_...

In the Linux kernel, the following vulnerability has been resolved: tipc: prevent sntunacked underflow on CONNACK tipcskconnprotorcv subtracts the peer-supplied connection ack count from the unsigned 16-bit send counter sntunacked without checking that it does not exceed the number of messages...

Astra Linux – vulnerability in linux-6.1

In the Linux kernel, the following vulnerability has been resolved: tipc: requires net admin for TIPCv2 netlink mutators TIPCv2 registers mutating generic-netlink operations without admin permission flags. Generic netlink only checks CAPNETADMIN when an operation sets GENLADMINPERM or...

Astra Linux – vulnerability in linux-6.1

In the Linux kernel, the following vulnerability has been resolved: tipc: fix infinite loop in tipcnlcompatdumpit The cmd-dumpit callback can return a negative errno, causing an infinite loop due to the whilelen condition. Since the loop never terminates, genlmutex is never released, and other...

kernel: tipc: require net admin for TIPCv2 netlink mutators

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC version 2 component. This vulnerability allows a local unprivileged attacker to bypass administrative permission checks when performing network link operations. Consequently, the attacker can modify critical TIPC...
