NVD Description

Note: Versions mentioned in the description apply only to the upstream libperf package and not the libperf package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

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

nvmet-auth: fix out-of-bounds write in nvmet_auth_challenge()

nvmet_auth_challenge() receives its output buffer as a void pointer. sizeof(*d) therefore evaluates to one with GCC and undercounts the fixed challenge header by 15 bytes. A short AUTH_RECEIVE buffer can pass the check before the challenge is copied past the end of its allocation.

Use the typed challenge pointer when calculating the response size.
