    Added Description In the Linux kernel, the following vulnerability has been resolved:

    nvmet: fix out-of-bounds access in nvmet_enable_port

    When trying to enable a port that has no transport configured yet,
    nvmet_enable_port() uses NVMF_TRTYPE_MAX (255) to query the transports
    array, causing an out-of-bounds access:

    [ 106.058694] BUG: KASAN: global-out-of-bounds in nvmet_enable_port+0x42/0x1da
    [ 106.058719] Read of size 8 at addr ffffffff89dafa58 by task ln/632
    […]
    [ 106.076026] nvmet: transport type 255 not supported

    Since commit 200adac75888, NVMF_TRTYPE_MAX is the default state as configured by
    nvmet_ports_make().
    Avoid this by checking for NVMF_TRTYPE_MAX before proceeding.
