What is CVE-2025-38139?

A vulnerability in the Linux kernel’s network file system could cause a buffer overflow due to improper resetting of the subrequest iterator during write operations. When the iterator is mismanaged, it may lead to inaccurate data handling, resulting in potential crashes or instability in the kernel, particularly visible through Kernel Address Sanitizer (KASAN) errors. This flaw underscores the importance of correctly managing subrequest data transfers to prevent unexpected behaviors in network operations.
