  "description": "In the Linux kernel, the following vulnerability has been resolved:  ksmbd: zero pipe read compound padding  Compound response handling extends the last response iov to an eight-byte boundary.  smb2_read_pipe() allocates only the payload size, so the alignment padding can expose up to seven bytes of uninitialized kernel heap memory.  Allocate the aligned size and clear the unused tail before pinning the response buffer.",
