Linux Distros Unpatched Vulnerability : CVE-2026-81736

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - If a BIND resolver has cached a tree of SVCB/HTTPS AliasMode records, and is then queried for the root of that tree, the resolver will spend disproportionate CP...

CVE-2026-81736: Excessive Platform Resource Consumption within a Loop

If a BIND resolver has cached a tree of SVCB/HTTPS AliasMode records, and is then queried for the root of that tree, the resolver will spend disproportionate CPU time constructing the response. This issue affects BIND 9 versions 9.18.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through...

Linux Distros Unpatched Vulnerability : CVE-2026-19668

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A BIND recursive resolver may experience excessive resource consumption if it encounters large numbers of a particular kind of invalid DNSSEC record. Default...

CVE-2026-53941

Inspektor Gadget (eBPF-based system inspection framework for Kubernetes and Linux hosts), versions 0.27.0 through 0.53.1 , is vulnerable to a Denial of Service triggered by an unprivileged container supplying a crafted /etc/ld.so.cache file while an uprobe-based gadget is active. The parser in pk...

CVE-2026-53941: Allocation of Resources Without Limits or Throttling

Inspektor Gadget is a set of tools and framework for data collection and system inspection on Kubernetes clusters and Linux hosts using eBPF. From 0.27.0 until 0.53.1, the uprobe library resolver can allow an unprivileged container to consume excessive CPU and block other containers from starting...

net: golang: Go net package: Denial of Service via long CNAME response in LookupCNAME

A flaw was found in the net package of Go golang, specifically when using the LookupCNAME function with the cgo DNS resolver. A remote attacker could exploit this by providing a very long Canonical Name CNAME response. This can trigger a double-free of C memory, leading to a crash and a Denial of...

Astra Linux – Vulnerability in unbound

A vulnerability called “Non-Responsive Delegation Attack” NRDelegation Attack has been discovered in various DNS resolution software. The NRDelegation Attack works by creating a malicious delegation with a significant number of non-responsive name servers. The attack begins by querying a resolver...

Astra Linux – Vulnerability in docker.io-app

Moby is an open-source container framework that is a key component of Docker Engine, Docker Desktop, and other distributions of container tools or runtimes. Moby’s networking implementation allows for multiple networks to be defined, each with its own IP address range and gateway. This feature is...

Astra Linux – Vulnerability in bind9

By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode the available memory to the point where named crashes occur due to lack of resources...

Astra Linux – Vulnerability in ldns

NLnet Labs’ ldns version 1.2.0, including versions up to and including 1.9.0, when used as a stub resolver over UDP, fails to match the query destination address and port with the response source address and port. Moreover, neither the query ID nor the nature of the query matches that of the...

Astra Linux – Vulnerability in bind9

By flooding the target resolver with queries that exploit this flaw, an attacker can significantly impair the resolver’s performance, effectively denying legitimate clients access to the DNS resolution service...

By spoofing the target resolver with responses that have a malformed ECDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode the available memory to the point where named crashes occur due to lack of resources...

Astra Linux – Vulnerability in bind9

If a BIND resolver performs DNSSEC validation and encounters a maliciously crafted zone, the resolver may consume excessive CPU resources. Authoritative-only servers are generally unaffected, although there are circumstances where authoritative servers may make recursive queries see:...
