Description
In the Linux kernel, the following vulnerability has been resolved:
NFSD: Fix NFSv3 SETATTR/CREATE's handling of large file sizes
iattr::ia_size is a loff_t, so these NFSv3 procedures must be
careful to deal with incoming client size values that are larger
than s64_max without corrupting the value.
Silently capping the value results in storing a different value
than the client passed in which is unexpected behavior, so remove
the min_t() check in decode_sattr3().
Note that RFC 1813 permits only the WRITE procedure to return
NFS3ERR_FBIG. We believe that NFSv3 reference implementations
also return NFS3ERR_FBIG when ia_size is too large.
Affected configurations
• linux linux kernel (< 5.4.295)
• linux linux kernel (>= 5.5 < 5.10.220)
• linux linux kernel (>= 5.11 < 5.15.24)
• linux linux kernel (>= 5.16 < 5.16.10)
• linux linux kernel 5.17
