CVE-2026-98805

A flaw was found in the Linux kernel's TIPC Transparent Inter-Process Communication module. A network attacker who intercepts cluster communications can achieve information disclosure and alter transmitted data. This vulnerability occurs because TIPC resets encryption sequence counters during pee...

N-Day Vulnerability Research Overview This project focuses on N-Day vulnerabilities in the Linux kernel, with an emphasis on understanding their lifecycle, analyzing their impact, and exploring mitigation strategies. N-Day vulnerabilities are publicly disclosed flaws that remain unpatched on many...

CVE-2026-99054

The Linux kernel contains a vulnerability in the tipc component where tipc_topsrv_stop() closes subscriber connections while the topology server's send and receive workqueues are still running. This race condition allows socket callbacks or subscription events to queue additional work, leading to...

EUVD-2026-108849

In the Linux kernel, the following vulnerability has been resolved: tipc: destroy topsrv workqueues before closing connections tipctopsrvstop closed subscriber connections while the topology server's send and receive workqueues were still running. Socket callbacks and subscription events could th...

CVE-2026-99053

The Linux kernel is vulnerable to a slab-use-after-free flaw within the tipc (TIPC) component. The root cause is that tipc_node_find_by_name() returns a node after releasing its RCU read lock without taking a reference. This creates a race condition where tipc_node_timeout() can free the node whi...

EUVD-2026-108848

In the Linux kernel, the following vulnerability has been resolved: tipc: hold a reference to nodes found by link name tipcnodefindbyname returns a node after dropping its RCU read lock without taking a reference. The LINKSET, LINKGET and LINKRESETSTATS handlers then lock and access the node,...

CVE-2026-98934

The Linux kernel contains a vulnerability where the seg6_make_flowlabel() function could be reached with a socket buffer (skb ) lacking both skb->dev and skb->sk pointers. This issue occurs when a TIPC UDP bearer sends a discovery message via an IPv4 route using seg6 encap while net.ipv6.se...

EUVD-2026-108906

In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: use skbgethashnet in seg6makeflowlabel Since commit d58e468b1112 "flowdissector: implements flow dissector BPF hook" skbflowdissect needs a net pointer, either from skb-dev, skb-sk, or since commit 3cbf4ffba5ee "net:...

CVE-2026-64563_EXP

CVE-2026-64563EXP For experimental research only. The code for prefetch and nperm the memory reference set.gdb needs to be configured is not attached, and since it has not been optimized, the hit probability is low. The author noticed that the vulnerability author has already released relevant...

CVE-2026-80866

A flaw was found in the Linux kernel's TIPC Transparent Inter-Process Communication subsystem. A busy-wait loop in the tipcexitnet function, intended to wait for UDP bearer cleanup, can consume excessive CPU cycles. This issue arises when the condresched function is ineffective, such as when a...

CVE-2026-98550

A flaw was found in the TIPC Transparent Inter-Process Communication subsystem of the Linux kernel. This flaw allows an attacker to cause a Denial of Service DoS by sending unexpected or duplicate group acknowledgment messages. Due to improper validation of incoming protocol messages, an internal...

Linux Distros Unpatched Vulnerability : CVE-2026-98550
