CVE-2026-96235
Description
A flaw was found in .NET. Due to an out-of-bounds write vulnerability, where data is written past the boundary of an allocated memory buffer, memory corruption can occur. A remote, unauthenticated attacker could exploit this issue over the network to achieve arbitrary code execution on the target system.
Statement
Red Hat rates this vulnerability as an Important severity flaw because an attacker can achieve remote arbitrary code execution, though exploitation requires user or service interaction to ingest malicious input. In Red Hat environments, applications running on the .NET runtime that process untrusted network data or external payloads are exposed to memory corruption. The potential impact is bounded by the security privileges of the account executing the affected .NET process.
Understanding the Weakness (CWE)
Integrity
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Write operations could cause memory corruption. In some cases, an adversary can modify control data such as return addresses in order to execute unexpected code.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
Attempting to access out-of-range, invalid, or unauthorized memory could cause the product to crash.
Other
Technical Impact: Unexpected State
Subsequent write operations can produce undefined or unexpected results.
