Description
A vulnerability was found in the Linux kernel's NFSD, specifically in the handling of large file sizes during NFSv3 SETATTR and CREATE operations. The ia_size field, being a signed 64-bit type, can lead to unexpected behavior when clients send size values larger than the maximum allowed. This improper handling can result in silent value capping, potentially leading to data corruption in file size management.
