bugzilla: 51868
CVE: NA

--------------------------------

[ Upstream commit a2c5bedb ]

When handling op->addr, it is using the buffer "tmpbuf" which has been
freed. This will trigger a use-after-free KASAN warning. Let's use
temporary variables to store op->addr.val and op->cmd.opcode to fix
this issue.
