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.
