It replaces the less informati...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: icmp: Fixed a NULL pointer dereferencing in icmptagvalidation. icmptagvalidation unconditionally dereferes the result of rcudereferenceinetprotosproto without checking for NULL. The inetprotos array is sparse—only about 15 out...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: sched: actconnmark: initialize struct tcife to prevent kernel leaks. In tcfconnmarkdump, the variable ‘opt’ was partially initialized using a specified initializer. As a result, the padding bytes remained uninitialized. The...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/dpmst: Fixed the check on the length of the MST sideband message body. The issue involved checking the length of the MST sideband message body; it must be at least 1 byte, taking into account the message body CRC also known a...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: can: ucan: Fix infinite loop caused by zero-length messages. If a faulty ucan device receives a message where the message length field is set to 0, then the driver will enter an infinite loop in ucanreadbulkcallback, causing the...

Astra Linux – Vulnerability in Ruby 2.5

A vulnerability was discovered in Ruby. The Ruby interpreter is vulnerable to the Marvin Attack. This attack allows the attacker to decrypt previously encrypted messages or forge signatures by exchanging a large number of messages with the vulnerable service...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: ila: Do not generate empty messages in ilaxlatnlcmdgetmapping. ilaxlatnlcmdgetmapping generates an empty skb, triggering a recent sanity check. Instead, an error code should be returned so that it can be processed by the user...

Astra Linux – Vulnerability in Netty

The Netty project is an event-driven, asynchronous network application framework. In versions prior to 4.1.86.Final, a StackOverflowError could occur when parsing a malformed message due to infinite recursion. This issue has been fixed in version 4.1.86.Final. There is no workaround, except by...

Astra Linux – Vulnerability in Thunderbird

The Matrix JavaScript SDK is the Matrix Client-Server SDK for JavaScript. Prior to version 19.7.0, an attacker working alongside a malicious home server could create messages that appeared to be sent by another person, without any indication such as a gray shield. Additionally, a sophisticated...

Astra Linux – Vulnerability in dpdk

A flaw was discovered in dpdk. This flaw allows a malicious vhost-user master to attach an unexpected number of fds as auxiliary data to VHOSTUSERGETINFLIGHTFD / VHOSTUSERSETINFLIGHTFD messages that are not closed by the vhost-user slave. By continuously sending such messages, the malicious...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: hns3: Fix for kernel crash when 1588 messages are received on HIP08 devices HIP08 devices do not register as ptp devices. As a result, hdev-ptp is NULL. However, the hardware can receive 1588 messages and set the HNS3RXDTSVL...

TLS 1.3 handshake messages incorrectly accepted across encryption level boundaries

Rustls accepted TLS 1.3 handshake messages sent at the wrong encryption level when they followed a key-changing message in the same record. For example, a plaintext EncryptedExtensions message packed into the same record as the ServerHello was accepted. RFC 8446 section 5.1 requires that handshak...

Summary IBM MQ has addressed a heap buffer underflow vulnerability in the queue manager's protocol handling that could allow a remote authenticated attacker to execute arbitrary code Vulnerability Details CVEID:CVE-2026-10858 DESCRIPTION: IBM MQ could allow an authenticated attacker to cause a...

CVE-2026-5132

Mattermost versions 11.9.x = 11.9.0, 11.8.x = 11.8.4, 11.7.x = 11.7.7, 10.11.x = 10.11.22 fail to limit size of unpacked SDP messages compressed with zlib, which allows attacker to deny service or crash server via sending many SDP messages that unpack to large size.. Mattermost Advisory ID:...

Security Bulletin: IBM MQ Java messaging is vulnerable to remote code execution (CVE-2026-12728)

Summary IBM MQ has addressed a deserialization filter bypass vulnerability in the IBM MQ Java client's distributed messaging component that could allow a remote authenticated attacker to execute arbitrary code by delivering crafted serialized messages that bypass the configured deserialization...
