CVE-2026-48510 MessagePack-CSharp: LZ4 decompression allocates from unbounded declared output lengths

MessagePack for C is a MessagePack serializer for C. Prior to 2.5.301 and 3.1.7, when MessagePack-CSharp decompresses Lz4Block or Lz4BlockArray payloads, it reads declared uncompressed lengths from the wire and allocates output buffers based on those lengths before validating that the compressed...

CVE-2026-48510

CVE-2026-48510 affects MessagePack-CSharp (C#) prior to 2.5.301 and 3.1.7. When decompressing Lz4Block or Lz4BlockArray payloads, the library reads declared uncompressed lengths from the wire and allocates output buffers before validating the data, allowing a small payload to trigger a large allo...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: erofs: Fix for lz4 inplace decompression Currently, EROFS can map another compressed buffer for inplace decompression, which was used to handle cases where some pages of compressed data are not actually in-place I/O. However, lik...

Out-of-bounds Read

Overview MessagePack is a MessagePackMsgPack Serializer for C.NET, .NET Core, Unity, Xamarin. Affected versions of this package are vulnerable to Out-of-bounds Read in the LZ4 decompression path for Lz4Block and Lz4BlockArray modes. An attacker can cause process termination or potentially access...

CVE-2026-45999

A flaw was found in the Linux kernel's EROFS Enhanced Read-Only File System component. A local user could provide a specially crafted EROFS image that triggers an unsigned underflow in the zerofslz4handleoverlap function during LZ4 inplace decompression. This vulnerability allows the system to re...
