CVE-2021-47107

CVE-2021-47107 : Linux kernel NFSD is affected by a buffer overflow in READDIR handling. If a client sends a very small READDIR count (e.g., 0), the new init_dirlist logic can underflow the buffer size calculation, causing XDR writing to exceed the allocated space. This underflow was exposed by a...
