wifi: iwlwifi: mvm: fix potential array out of bounds access

Account for IWL_SEC_WEP_KEY_OFFSET when needed while verifying key_len size in iwl_mvm_sec_key_add().

CVSS

Version: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
Base score: 7.1

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.14%
Percentile among all scored CVEs: 3
Score date: 10/5/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
