The vulnerability of the make_task_dead() function in the kernel/exit.c module of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the maketaskdead function in the kernel/exit.c module of the Linux operating system’s kernel relates to the simultaneous release of the same resource or descriptor. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...

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...

CVE-2026-86205

h3 versions before 2.0.1-rc.18 contain an open redirect vulnerability in the redirectBack utility that fails to sanitize protocol-relative paths in the Referer header pathname. Attackers can craft a same-origin URL with a double-slash path segment that passes origin validation but produces a...

CVE-2026-86251

h3 versions before 1.15.9 contain a path traversal vulnerability in the serveStatic utility. A double-decoding flaw allows a request path containing double-encoded dot sequences e.g. %252e%252e to be decoded to %2e%2e, which survives resolveDotSegments because that function only checks for litera...

CVE-2026-86251 h3 before 1.15.9 Path Traversal via Double Decoding

CVE-2026-86251

Versions of h3 before 1.15.9 contain a path traversal vulnerability in the serveStatic utility. The root cause is a double-decoding flaw : a request path containing double-encoded dot sequences (e.g. %252e%252e) decodes to %2e%2e, which survives the resolveDotSegments() function because it only c...
