CVE-2026-46385
iskorotkov/avro: CPU Exhaustion in Avro Decoder
Overview
Description
iskorotkov/avro is a fast Go Avro codec. Prior to 2.33.0, the Avro array and map decoders looped over an attacker-controlled block-count value without checking the underlying reader's error state inside the loop body. Reader.ReadBlockHeader returns the count as a Go int, which is 64-bit on amd64 / arm64 targets — so a producer can declare a block of up to math.MaxInt64 (~9.2 × 10¹⁸) elements followed by EOF (or any truncated payload), and the decoder will attempt that many no-op iterations before propagating the error. The realistic ceiling is "indefinite until the worker is killed externally" — a single hostile payload pins a CPU core until the process is OOM-killed, deadline-cancelled, or terminated. Remote, unauthenticated denial-of-service. This vulnerability is fixed in 2.33.0.

Action Type Old Value New Value Added Translation Title: avro de iskorotkov, Description: iskorotkov/avro es un códec Avro rápido para Go. Antes de la versión 2.33.0, los decodificadores de array y mapa de Avro iteraban sobre un valor de conteo de bloques controlado por un atacante sin verificar el estado de error del lector subyacente dentro del cuerpo del bucle. Reader.ReadBlockHeader devuelve el conteo como un entero de Go, que es de 64 bits en objetivos amd64 / arm64 - por lo que un productor puede declarar un bloque de hasta math.MaxInt64 (~9.2 × 10¹?) elementos seguido de EOF (o cualquier carga útil truncada), y el decodificador intentará esa cantidad de iteraciones sin operación antes de propagar el error. El límite realista es 'indefinido hasta que el trabajador sea eliminado externamente' - una única carga útil hostil fija un núcleo de CPU hasta que el proceso sea eliminado por OOM, cancelado por plazo o terminado. Denegación de servicio remota, no autenticada. Esta vulnerabilidad está corregida en la versión 2.33.0. -

Action Type Old Value New Value Added Description iskorotkov/avro is a fast Go Avro codec. Prior to 2.33.0, the Avro array and map decoders looped over an attacker-controlled block-count value without checking the underlying reader's error state inside the loop body. Reader.ReadBlockHeader returns the count as a Go int, which is 64-bit on amd64 / arm64 targets — so a producer can declare a block of up to math.MaxInt64 (~9.2 × 10¹⁸) elements followed by EOF (or any truncated payload), and the decoder will attempt that many no-op iterations before propagating the error. The realistic ceiling is "indefinite until the worker is killed externally" — a single hostile payload pins a CPU core until the process is OOM-killed, deadline-cancelled, or terminated. Remote, unauthenticated denial-of-service. This vulnerability is fixed in 2.33.0. Added CVSS V4.0 AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X Added CWE CWE-400 Added Reference https://github.com/iskorotkov/avro/security/advisories/GHSA-w8j3-pq8g-8m7w
