Subject: [PATCH v3 1/4] station: check return of handshake_state_set_pmksa
Date: Mon,  9 Mar 2026 09:57:43 -0700	[thread overview]
Message-ID: <20260309165746.2073055-1-prestwoj@gmail.com> (raw)

If this fails num_pmkids and pmkids would get set, but to an
uninitialized buffer. This would then fail to build the handshake
object later when copying the PMKID.
