Remote Code Execution Risk in Linux Kernel Due to Key Handling Flaw

CVE-2026-80924

What is CVE-2026-80924?

A vulnerability exists in the Linux Kernel's handling of derived key buffers within the cryptographic services. The functions responsible for preparing encryption and checksum processes unintentionally free the memory with improperly secured key material. As a result, sensitive data may persist in memory after deallocation, creating a potential pathway for exploitation. Implementing the recommended fixes ensures that derived keys are handled securely without leaving sensitive information exposed.
