crypto/x509: golang: Denial of Service due to excessive resource consumption via crafted certificate

A flaw was found in golang. A remote attacker could exploit this vulnerability by providing a specially crafted certificate during the error string construction process within the HostnameError.Error function. This flaw, caused by unbounded string concatenation, leads to excessive resource...

Next.js has Unbounded Memory Consumption via PPR Resume Endpoint

A denial of service vulnerability exists in Next.js versions with Partial Prerendering PPR enabled when running in minimal mode. The PPR resume endpoint accepts unauthenticated POST requests with the Next-Resume: 1 header and processes attacker-controlled postponed state data. Two closely related...

urllib3: urllib3: Unbounded decompression chain leads to resource exhaustion

A flaw was found in urllib3 Python library that could lead to a Denial of Service condition. A remote, malicious server can exploit this flaw by responding to a client request with an HTTP message that uses an excessive number of chained compression algorithms. This unlimited decompression chain...

Denial Of Service (DoS)

Next.js is vulnerable to a Denial of Service DoS vulnerability. The vulnerability is due to unbounded request body buffering and unbounded decompression in the Partial Prerendering PPR resume endpoint, which allows an attacker to send specially crafted unauthenticated POST requests or compressed...

CVE-2026-23881

Kyverno is a policy engine designed for cloud native platform engineering teams. Versions prior to 1.16.3 and 1.15.3 have unbounded memory consumption in Kyverno's policy engine that allows users with policy creation privileges to cause denial of service by crafting policies that exponentially...

CVE-2026-22258

CVE-2026-22258 affects Suricata (IDS/IPS/NSM). Before versions 8.0.3 and 7.0.14, crafted DCERPC traffic can trigger unbounded buffering, causing memory exhaustion and process termination. While initially observed over UDP, TCP and SMB are also considered vulnerable; however, DCERPC/TCP defaults l...

golang: archive/tar: Unbounded allocation when parsing GNU sparse map

A flaw was found in the archive/tar package in the Go standard library. tar.Reader does not set a maximum size on the number of sparse region data blocks in GNU tar pax 1.0 sparse files. A specially crafted tar archive with a pax header indicating a big number of sparse regions can cause a Go...

EUVD-2025-206398

Issue summary: A TLS 1.3 connection using certificate compression can be forced to allocate a large buffer before decompression without checking against the configured certificate size limit. Impact summary: An attacker can cause per-connection memory allocations of up to approximately 22 MiB and...
