In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> nvmet: fix out-of-bounds access in nvmet_enable_port<br /> <br /> When trying to enable a port that has no transport configured yet,<br /> nvmet_enable_port() uses NVMF_TRTYPE_MAX (255) to query the transports<br /> array, causing an out-of-bounds access:<br /> <br /> [ 106.058694] BUG: KASAN: global-out-of-bounds in nvmet_enable_port+0x42/0x1da<br /> [ 106.058719] Read of size 8 at addr ffffffff89dafa58 by task ln/632<br /> [...]<br /> [ 106.076026] nvmet: transport type 255 not supported<br /> <br /> Since commit 200adac75888, NVMF_TRTYPE_MAX is the default state as configured by<br /> nvmet_ports_make().<br /> Avoid this by checking for NVMF_TRTYPE_MAX before proceeding.
