A vulnerability in the Linux kernel's SMB client implementation could cause file hole punching operations to incorrectly report data ranges. Specifically, punching a hole after a large buffered write may leave the range reported as data instead of a hole, due to dirty data being written back after the punch operation. This issue has been resolved by flushing dirty data before invalidating the page cache and issuing the FSCTL_SET_ZERO_DATA command.
