This patch adds the following additional checks to canmapfrag:...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

A flaw was discovered in the Linux kernel’s NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packets when using NVMe over TCP. This can lead to the NVMe driver dereferencing a NULL pointer, resulting in kernel panic and a denial of service...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: In mptcp, the task of cleaning up subflows has been moved to mptcpDestroyCommon. If the creation of a mptcp socket fails due to the CGROUPINETSOCKCREATE eBPF program, the MPTCP protocol ends up leaking all subflows. This related...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: TCP: Fixed the issue where “tcpmtupprobesuccess” was displayed instead of “wrong sndcwnd”. The syzbot received a new report 1, which finally pointed to a very old bug. This bug was addressed in the initial support for MTU probing...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: fixed a memory leak in tcpconnrequest. If inetcskreqskqueuehashadd returns false, tcpconnrequest will return without freeing the dst memory, which was allocated in afops-routereq. Here is the stack trace for the issue:...

Core Component Oracle Coherence Full Control

The vulnerability of the Core component of the Oracle Coherence data processing software is related to improper code generation management. Exploiting this vulnerability can allow an attacker to gain full control over the application using the TCP protocol...

CVE-2026-82435: Memory Allocation with Excessive Size Value

Description The worker's Netty message decoder is installed ahead of the SASL authentication handlers in the pipeline and acts on frames before any authentication has taken place. It allocated buffers sized from a length field carried in the frame, so a single frame from an unauthenticated peer...

CVE-2026-91143: Authentication Bypass Using an Alternate Path or Channel

goproxy through 15.3 fails to apply HTTP proxy basic authentication to CONNECT tunnel requests, allowing unauthenticated clients to bypass credential requirements. Attackers can issue CONNECT requests to establish tunnels through the authenticated proxy without providing credentials, enabling...

SUSE CVE-2026-89480

In the Linux kernel, the following vulnerability has been resolved: nvme-tcp: reject a read that transferred too few bytes nvmetcprecvdata completes a request once the current C2HData PDU has been consumed. Nothing compares the total bytes received against the length the command asked for: struct...

SUSE CVE-2026-89481

In the Linux kernel, the following vulnerability has been resolved: nvme-tcp: fix host memory disclosure on R2T for a read command nvmetcphandler2t does not check the direction of the request the R2T refers to. A malicious controller can send an R2T for a READ and the host will answer it:...

Linux Distros Unpatched Vulnerability : CVE-2026-89481

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - nvme-tcp: fix host memory disclosure on R2T for a read command nvmetcphandler2t does not check the direction of the request the R2T refers to. A malicious...

Linux Distros Unpatched Vulnerability : CVE-2026-89482

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - nvme-tcp: do not accept C2HData based on blkrqpayloadbytes alone Commit 25e5cb780e62 nvme-tcp: fix possible crash in writezeroes processing established that...

A High-Throughput FPGA Architecture for Real-Time TCP-SYN Scan Detection

TCP-SYN port scanning often precedes cyber-attacks, and early detection of scanner fingerprints embedded in packet headers can provide timely intrusion alerts. Existing approaches are either too computationally expensive for line-rate operation or limited to offline analysis. This brief presents ...

Nothing compares the...

CVE-2026-89481

A flaw was found in the Linux kernel's NVMe Non-Volatile Memory Express over TCP nvme-tcp component. A malicious NVMe controller can exploit this vulnerability by sending a Ready to Transfer R2T command for a read request. The host system, failing to properly validate the request direction, will...

CVE-2026-89482

A flaw was found in the nvme-tcp module of the Linux kernel. This vulnerability arises from improper handling of C2HData for REQOPWRITEZEROES commands, where the system fails to adequately validate the data length. A remote attacker could exploit this by sending specially crafted C2HData, leading...

CVE-2026-89480

A flaw was found in the NVMe-TCP implementation of the Linux kernel. This vulnerability occurs when the system completes a data read request even if the connected controller transfers fewer bytes than expected. As a result, the user application receives a mix of legitimate and stale data,...

CVE-2026-80788

A flaw was found in the Linux kernel's nvmet-tcp component. A remote attacker can send a specially crafted command with an oversized Scatter-Gather List SGL allocation. This can lead to an excessive memory allocation, triggering a kernel warning. On systems configured to panic on warnings, this...
