CVE-2026-50256

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between the X server and the libXfont2 library's maximum font name length can cause a stack buffer overflow during font alias resolution. The server allocates a 256 byte stack buffer but libXfont2's alias...

CVE-2026-50256

The CVE affects the X.Org X server and Xwayland. A mismatch between the server and libXfont2 regarding maximum font name length (server-allocated 256-byte stack buffer vs libXfont2 name length up to 1024 bytes) allows a font alias name of 257–1023 bytes to overflow the stack during alias resoluti...

CVE-2026-50256 Xorg-x11-server: xorg-x11-server-xwayland: xorg-x11-server: stack buffer overflow in font alias resolution due to libxfont2 name length mismatch

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between the X server and the libXfont2 library's maximum font name length can cause a stack buffer overflow during font alias resolution. The server allocates a 256 byte stack buffer but libXfont2's alias...

BIT-AIRFLOW-2026-41084 Apache Airflow: API authorization bypass: bulk TaskInstances allows cross-DAG mutation

A bug in Apache Airflow's bulk Task Instances API PATCH/DELETE /api/v2/dags/dagid/dagRuns/dagrunid/taskInstances evaluated authorization against the dagid resolved from the URL path while operating on the dagid / dagrunid extracted from request-body entity fields. An authenticated UI/API user wit...

Starlette - Improper Validation of Unsafe Equivalence in Input

A flaw was found in Starlette, a lightweight ASGI Asynchronous Server Gateway Interface framework. A remote attacker could exploit this vulnerability by sending a specially crafted HTTP Host request header. This malformed header could cause the request.url to be incorrectly reconstructed, leading...

GHSA-2GCR-MFCQ-WCC3 Hono: app.mount() strips mount prefix using undecoded path, causing incorrect routing for percent-encoded paths

Summary app.mount strips the mount prefix from the incoming request path using the raw URL pathname, while route matching is performed against the percent-decoded path. This inconsistency causes the prefix to be stripped at the wrong position when the path contains percent-encoded multi-byte...

php: NULL pointer dereference in php_mb_check_encoding() via mb_ereg_search_init()

A flaw was found in PHP. When an attacker input can influence the encoding passed to mbregexencoding and the application subsequently uses mbregex search APIs, a NULL pointer dereference can occur due to a mismatch between the Oniguruma and mbfl encoding support. This issue can cause a crash in t...

HCL iControl was affected by Weak Input Validation vulnerability. This weakness is caused during implementation of an architectural security tactic. Received input that is expected to be of a certain type, but it does not validate or incorrectly validates that the input is actually of the expecte...

SUSE CVE-2026-45681

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, the per-CPU message-buffer fallback path uses a 256-byte backup buffer but preserves the original payload size, which can be up to 8KB. If a CPU mismatch occurs, OBI can...

Description-Code Inconsistency in Real-World MCP Servers: Measurement, Detection, and Security Implications

The Model Context Protocol MCP has emerged as a critical standard empowering Large Language Models LLMs to utilize external tools. In this ecosystem, LLMs rely on natural language descriptions provided by MCP servers to select and execute functions. This interaction implicitly assumes that tool...
