Severity ?
7.1 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
Details

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

objtool, nvmet: Fix out-of-bounds stack access in nvmet_ctrl_state_show()

The csts_state_names[] array only has six sparse entries, but the iteration code in nvmet_ctrl_state_show() iterates seven, resulting in a potential out-of-bounds stack read. Fix that.

Fixes the following warning with an UBSAN kernel:

vmlinux.o: warning: objtool: .text.nvmet_ctrl_state_show: unexpected end of section
