CVE-2026-48109

CVE-2026-48109 affects MessagePack-CSharp in the optional LZ4 decompression path (Lz4Block, Lz4BlockArray). The vulnerability stems from a deprecated fast-decompression algorithm that does not enforce a source-length bound, enabling a remote attacker to craft payloads with manipulated LZ4 token/l...

CVE-2026-48510

CVE-2026-48510 affects MessagePack-CSharp. Prior to versions 2.5.301 and 3.1.7, during Lz4Block/Lz4BlockArray decompression the library reads declared uncompressed lengths from the wire and allocates output buffers before validating payload integrity or expansion reasonableness. This can allow a ...

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...

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...

Amazon Linux 2 : rust, --advisory ALAS2-2026-3225 (ALAS-2026-3225)

The version of rust installed on the remote host is prior to 1.93.0-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3225 advisory. Decompressing invalid LZ4 data can leak data from uninitialized memory, or can leak content from previous decompression operations wh...
