Buffer Overflow Vulnerability in Linux Kernel NFSv3 Implementation
CVE-2022-50345
What is CVE-2022-50345?
A vulnerability exists in the Linux kernel's NFSv3 implementation, where an attacker could exploit send buffer overflow conditions. This occurs when a client sends a malformed RPC Call header embedded in an RPC record that exceeds expected sizes. The resulting shrinkage of the send buffer can lead to a situation where the maximum payload size cannot be fully constructed due to the lack of available memory space. This behavior can impact data integrity and server performance, making it critical for administrators to apply patches and updates to ensure system security.
