net/http: golang: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service

A flaw was found in the net/http component of the Go standard library. When a server is configured to support unencrypted HTTP/2, it reads initial bytes from new connections to detect the HTTP/2 client preface. However, the ReadHeaderTimeout is not correctly applied during this process. This...

encoding/xml: golang: Go: Denial of Service via XML decoding recursion depth issue

A flaw was found in the encoding/xml package of Go. The DecodeElement function failed to correctly track recursion depth, which could lead to stack exhaustion. A remote attacker could exploit this vulnerability by providing a specially crafted XML input, resulting in a Denial of Service DoS for t...

net/url: golang: golang net/url: Denial of Service from quadratic complexity in path resolution

A flaw was found in net/url, a component of golang. This vulnerability arises when resolving relative paths that contain numerous parent directory '..' segments. A remote attacker could exploit this by providing a specially crafted path, leading to quadratic time complexity and excessive memory...

CVE-2026-11573

CVE-2026-11573 affects Qt's QtXml module, specifically QDomDocument::toByteArray(). The root cause is uncontrolled recursion when serializing deeply nested untrusted XML (e.g., an SVG file), which exhausts the call stack and crashes the application. The impact is limited to denial of service (ava...

x86: improper handling of HVM emulation return codes

ISSUE DESCRIPTION A guest with a PCI device assigned that has at least a BAR on the IO port space can trigger a BUG in Xen. IMPACT Passing through a PCI device with at least one BAR in IO address space to unprivileged HVM guests can result in a Denial of Service DoS affecting the entire host...

CVE-2026-74860

CVE-2026-74860 affects libxml2 when compiled with Python bindings enabled. A remote attacker can supply a specially crafted XML document containing a DTD with enumerated attribute values , triggering a double-free in the SAX attributeDecl callback handler (a string is freed twice). The flaw resul...

CVE-2026-74860 Libxml2: double-free/uaf in libxml2 python bindings

A flaw was found in libxml2 with Python bindings enabled. A remote attacker could exploit this vulnerability by providing a specially crafted XML document containing a Document Type Definition DTD with enumerated attribute values. This triggers a double-free error in the SAX attributeDecl callbac...
