CVE-2026-98925

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter sockmap subsystem. This flaw allows a local attacker to cause a Denial of Service DoS when redirecting network traffic back to the originating socket. The kernel improperly double-counts sequence numbers for received TCP Transmissi...

PLANET IGS-6325-16P4S Improper Validation of Integrity Check Value (CVE-2023-48795)

The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted from the extension negotiation message, and a client and server may consequently end up with a connecti...

CVE-2026-19735 Predictable TCP initial sequence numbers when the RFC 6528 secret key generation fails silently in the Zephyr TCP stack

The RFC 6528 initial-sequence-number implementation in subsys/net/ip/tcp.c derived every TCP ISN from SHA-256uniquekey || four-tuple plus a uptime-derived offset, where uniquekey is a 128-bit secret filled once by syscsrandget. The return value of that call was discarded and the once guard was...

CVE-2026-19735

The Zephyr TCP stack contains a vulnerability where the RFC 6528 initial-sequence-number (ISN) implementation may use predictable values. If the sys_csrand_get() call fails during early boot (e.g., due to -ENODEV or -EIO from the entropy driver), the system fails to catch the error and leaves the...

The Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ crlsa-20245297 advisory. edk2: Predictable TCP Initial Sequence Numbers CVE-2023-45236 edk2: Use of a Weak PseudoRandom Number Generator CVE-2023-45237 edk2: Temporary DoS...

CVE-2026-88778

Citrix NetScaler ADC and NetScaler Gateway are vulnerable to a TCP Initial Sequence Number (ISN) prediction flaw. The issue affects appliances with TCP-based virtual servers (such as HTTP, SSL, or TCP) where Enhanced ISN Generation is disabled. This vulnerability allows for predictable sequence n...

Astra Linux – Vulnerability in gnutls28

A flaw was discovered in gnutls. A remote attacker could exploit a issue in the Datagram Transport Layer Security DTLS packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. Thi...

Rockwell Automation CompactLogix Improper Validation of Integrity Check Value (CVE-2025-11694)

A security issue exists within the affected CompactLogix 5370 controllers due to missing validation of sequence numbers and source IP addresses in the CIP protocol. An attacker can abuse the exposed Connection IDs visible on the controller's web interface to send forged CIP packets, resulting in ...

CVE-2026-64432

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: validate Dirty Page Table capacity in logreplay copylcns In the analysis pass of $LogFile journal replay, logreplay copies LCNs from each action log record into an existing Dirty Page Table DPT entry without bounding th...

CVE-2026-63834

In the Linux kernel, the following vulnerability has been resolved: batman-adv: tpmeter: restrict number of unacked list entries When the unackedlist is unbound, an attacker could send messages with small lengths and appropriated seqno + gaps to force the receiver to allocate more and more...

CVE-2026-63834 batman-adv: tp_meter: restrict number of unacked list entries

In the Linux kernel, the following vulnerability has been resolved: batman-adv: tpmeter: restrict number of unacked list entries When the unackedlist is unbound, an attacker could send messages with small lengths and appropriated seqno + gaps to force the receiver to allocate more and more...

CVE-2026-63834

The CVE concerns the Linux kernel’s batman-adv tp_meter: unacked_list can be pressured to grow (via crafted small messages, seqno gaps) if the list is unbounded. The result is potential out-of-memory or high CPU usage from scanning a large unacked_list. If a limit is applied, the implementation m...
