tmem: consistently make pool_id a uint32_t
|
|
|
|
Treating it as an int could allow a malicious guest to provide a
|
|
negative pool_Id, by passing the MAX_POOLS_PER_DOMAIN limit check and
|
|
allowing access to the negative offsets of the pool array.
|
|
|
|
This is part of XSA-15 / CVE-2012-3497.
