In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
net: mana: Skip redundant detach on already-detached port<\/p>\n
When mana_per_port_queue_reset_work_handler() runs after a previous
\ndetach succeeded but attach failed, the port is left in a detached
\nstate with apc->tx_qp and apc->rxqs already freed. Calling
\nmana_detach() again unconditionally leads to NULL pointer dereferences
\nduring queue teardown.<\/p>\n
Add an early exit in mana_detach() when the port is already in
\ndetached state (!netif_device_present) for non-close callers, making
\nit safe to call idempotently. This allows the queue reset handler and
\nother recovery paths to simply retry mana_attach() without redundant
\nteardown.<\/p>\n","protected":false},"excerpt":{"rendered":"
