CVE-2026-43383
A flaw was found in the Linux kernel's TCP MD5 signature option. This vulnerability allows a remote attacker to perform timing attacks due to a non-constant-time comparison of Message Authentication Codes MACs. By observing the time taken for MAC comparisons, an attacker could potentially infer...
GHSA-H9HM-M2XJ-4RQ9 Zebra has Permanent Block Discovery Halt via Gossip Queue Saturation and Syncer Poisoning
Summary A composite denial-of-service vulnerability in Zebra's block discovery pipeline allows an unauthenticated remote attacker to permanently halt all new block discovery on a targeted node. The attack exploits three independent weaknesses in the gossip, syncer, and download subsystems — all...
CVE-2026-43384
In the Linux kernel, the following vulnerability has been resolved: net/tcp-ao: Fix MAC comparison to be constant-time To prevent timing attacks, MACs need to be compared in constant time. Use the appropriate helper function for this...
CVE-2026-43383
CVE-2026-43383 affects the Linux kernel’s TCP MD5 signature handling. The root cause is a non-constant-time MAC comparison, enabling potential timing attacks. The vulnerability is addressed by changing the MAC comparison to a constant-time implementation using the appropriate helper function. The...
SUSE CVE-2026-43194
In the Linux kernel, the following vulnerability has been resolved: net: consume xmit errors of GSO frames udpgrofrglist.sh and udpgrobench.sh are the flakiest tests currently in NIPA. They fail in the same exact way, TCP GRO test stalls occasionally and the test gets killed after 10min. These...
CVE-2026-43198
A flaw was found in the Linux kernel. A race condition exists in the TCP Transmission Control Protocol IPv6 Internet Protocol version 6 socket handling, specifically within the tcpv6synrecvsock function. This occurs because a child socket becomes visible in the TCP hash table before its...
CVE-2026-43194
A flaw was found in the Linux kernel's networking subsystem. Specifically, the kernel incorrectly processes transmit errors for Generic Segmentation Offload GSO frames. When a single segment within a GSO frame is lost, the system may misinterpret this as a complete loss of the entire frame. This...
CVE-2026-43254
In the Linux kernel, the following vulnerability has been resolved: ovpn: tcp - fix packet extraction from stream When processing TCP stream data in ovpntcprecv, we receive large cloned skbs from strprcv that may contain multiple coalesced packets. The current implementation has two bugs: 1. Head...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the CIFS component where cifs tcp ses lock was used to protect various objects, including tcon fields, instead of using more granular locks. This caused unnecessary...
CVE-2026-6525
A flaw was found in the IEEE 802.11 dissector in Wireshark. This issue occurs when malformed packets are decoded from a pcap file or the network, causing a NULL pointer dereference, resulting in a denial of service. Mitigation If the IEEE 802.11 protocol dissector is not being used, it can be...
CVE-2026-7730
A weakness has been identified in privsim mcp-test-runner 0.2.0. Impacted is the function childprocess.spawn of the file src/index.ts of the component MCP Interface. Executing a manipulation of the argument command can lead to os command injection. The attack may be launched remotely. The exploit...

In the Linux kernel, the following vulnerability has been resolved: net: use skbheaderpointer for TCPv4 GSO fragoff check Syzbot reported a KMSAN uninit-value warning in gsofeaturescheck called from netifskbfeatures 1. gsofeaturescheck reads iph-fragoff to decide whether to clear mangleidfeatures...
Wireshark 2.2.x < 2.2.1 Multiple Vulnerabilities (macOS)
The version of Wireshark installed on the remote macOS / Mac OS X host is prior to 2.2.1. It is, therefore, affected by multiple vulnerabilities as referenced in the wireshark-2.2.1 advisory. - In Wireshark 2.2.0, the NCP dissector could crash, triggered by packet injection or a malformed capture...
[SECURITY] Fedora 42 Update: miniupnpd-2.3.10-1.fc42
The MiniUPnP daemon is an UPnP IGD & PCP/NAT-PMP daemon for gateway routers. UPnP IGD & PCP/NAT-PMP are used to improve internet connectivity for devices behind a NAT router. Any peer to peer network application such as games, IM, etc. can benefit from a NAT router supporting UPnP IGD & PCP/NAT-P...
FreeBSD 安全漏洞
FreeBSD is a Unix-like operating system developed by the FreeBSD Foundation. FreeBSD has security vulnerabilities; these vulnerabilities stem from incorrect packet validation, which leads to infinite recursion when parsing SCTP block parameters. This can result in stack overflows and crashes...
ovn: ovn: Heap Over-Read in ICMP Error Response Generation
When generating an ICMP Destination Unreachable or Packet Too Big response, the handler copies a portion of the original packet into the ICMP error body using the IP header's self-declared total length iptotlen for IPv4, ip6plen for IPv6 without validating it against the actual packet buffer size...
