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.
