OpenTelemetry dotnet: Unbounded `grpc-status-details-bin` parsing in OTLP/gRPC retry handling

Summary When exporting telemetry over gRPC using the OpenTelemetry Protocol OTLP, the exporter may parse a server-provided grpc-status-details-bin trailer during retry handling. Prior to the fix, a malformed trailer could encode an extremely large length-delimited protobuf field which was used...

OpenTelemetry .NET 安全漏洞

OpenTelemetry .NET is the .NET client of OpenTelemetry by OpenTelemetry Inc. There were security vulnerabilities in the version of OpenTelemetry .NET from 1.13.1 to 1.15.2. These vulnerabilities stemmed from the gRPC exporter’s ability to parse the grpc-status-details-bin trailer provided by the...

CVE-2026-31435

A flaw was found in the Linux kernel's netfs component. Under certain circumstances, during a read retry operation, the system may incorrectly abandon subrequests. This issue arises because a pointer subreq used in the abandonment process can be uninitialized or point to invalid memory. An attack...
