Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
