kernel: NFSD: Fix ia_size underflow

A vulnerability was found in the Linux kernel's NFSD, where an underflow in the iasize field can occur due to incorrect handling of file size types. When an NFS client sends a file size greater than the maximum value the system can handle, it can lead to an underflow in the iasize variable, causi...

kernel: NFSD: Fix the behavior of READ near OFFSET_MAX

A vulnerability was found in the Linux kernel's NFSD, where improper handling of read requests near the maximum offset can lead to an integer overflow. When a client attempts to read from a near-maximum offset, it causes the server to return an invalid NFS error, resulting in indefinite retries b...

kernel: NFSD: Fix NFSv3 SETATTR/CREATE's handling of large file sizes

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 iasize field, being a signed 64-bit type, can lead to unexpected behavior when clients send size values larger than the maximum allowed. This...
