Subject: [PATCH] hw/nvme: fix leak of uninitialized memory in io_mgmt_recv
|
|
|
|
cheery-pick from 6a22121c4f25b181e99479f65958ecde65da1c92
|
|
|
|
Yutaro Shimizu from the Cyber Defense Institute discovered a bug in the
|
|
NVMe emulation that leaks contents of an uninitialized heap buffer if
|
|
subsystem and FDP emulation are enabled.
