CVE-2026-31431

copy.fail — AFALG AEAD splice primitive CVE-2026-31431 Overview This project is a C port of the original Python prototype, by offsecguy. It leverages the Linux kernel crypto API AFALG using: authencesnhmacsha256,cbcaes AEAD mode MSGMORE flag splice system call The technique feeds data from a...

copyfailautopatch

copyfailautopatch Detect and optionally mitigate CVE-2026-31431 "Copy Fail" on a Linux host. The vulnerability is a page-cache write primitive reachable through the AFALG socket family using the authencesnhmacsha256,cbcaes AEAD transform. This script reproduces the same primitive Theori...

CVE-2026-31431

🐞 CVE-2026-31431 - Copy Fail A logic flaw in authencesn chained through AFALG and splice into a controlled 4-byte write in the page cache of any readable file on the system. No race condition, no offsets, no compiled payload. The same 732-byte script gains root on every Linux distribution since...

CVE-2026-80852

In the Linux kernel, the following vulnerability has been resolved: tls: device: fix out-of-bounds write in tlsappendfrag Found with syzkaller and a local syzbot instance running on top of a netdevsim TLS offload emulation; tlsdevice.c is otherwise only reachable on a machine with a NIC that...

CVE-2026-81334

darknet subscripts its layer array with an index taken from a configuration file without checking it against the array's length. The array is allocated in src-lib/darknetnetwork.cpp as xcallocnet.n, sizeofDarknet::Layer, sized to exactly the number of layer sections the file declares. The shortcu...

CVE-2026-18504

A flaw was found in fastify. A remote attacker can bypass schema validation when a request body schema targets a root primitive value. This occurs because the validation process may coerce a JSON string into an expected type, but the original unvalidated string is then passed to the application...

CVE-2026-21751

HCL Hive is affected by a cryptographic primitive with a risky implementation which could allow an attacker unauthorized lateral compromise or widespread credential leakage if a single internal component is breached...

CVE-2025-68833 HCL Hive is affected by use of a cryptographic primitive with a risky implementation

HCL Hive Keycloak IAM Instance is affected by insufficient granularity of access control which could allow an attacker unauthorized access to resources...

CVE-2026-21751

HCL Hive is affected by a cryptographic primitive with a risky implementation , which could allow an attacker to achieve unauthorized lateral compromise or widespread credential leakage if a single internal component is breached. The vulnerability is rated CVSS 3.1 7.4 (HIGH) with a network attac...

CVE-2026-18504

fastify is a fast and low overhead web framework for Node.js. Versions of fastify before 5.12.1 are affected by a schema validation bypass when a request body schema targets a root primitive value. When the schema validates a top-level primitive such as an integer, Ajv can coerce a JSON string in...

CVE-2026-18504

fastify versions before 5.12.1 suffer a schema validation bypass: when a route schema targets a root primitive (e.g., integer), Ajv coerces the input type but Fastify passes the original uncoerced value to handlers, letting invalid data reach application logic. Upgrade to 5.12.1; no workarounds e...

CVE-2026-18504 fastify vulnerable to schema validation bypass via root primitive coercion mismatch

fastify is a fast and low overhead web framework for Node.js. Versions of fastify before 5.12.1 are affected by a schema validation bypass when a request body schema targets a root primitive value. When the schema validates a top-level primitive such as an integer, Ajv can coerce a JSON string in...

PT-2026-77312

Name of the Vulnerable Software and Affected Versions fastify versions prior to 5.12.1 Description A schema validation bypass occurs when a request body schema targets a root primitive value.
