In the Linux kernel, the following vulnerability has been resolved:
net: mana: Skip redundant detach on already-detached port
When mana per port queue reset work handler() runs after a previous
detach succeeded but attach failed, the port is left in a detached
state with apc->tx qp and apc->rxqs already freed. Calling
mana detach() again unconditionally leads to NULL pointer dereferences
during queue teardown.
Add an early exit in mana detach() when the port is already in
detached state (!netif device present) for non-close callers, making
it safe to call idempotently. This allows the queue reset handler and
other recovery paths to simply retry mana attach() without redundant
teardown.
