- Summary
- ksmbd: transport_ipc: validate payload size before reading handle
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: transport_ipc: validate payload size before reading handle
handle_response() dereferences the payload as a 4-byte handle without verifying that the declared payload size is at least 4 bytes. A malformed or truncated message from ksmbd.mountd can lead to a 4-byte read past the declared payload size. Validate the size before dereferencing.
This is a minimal fix to guard the initial handle read.
