CVE-2022-50164: wifi: iwlwifi: mvm: fix double list_add at iwl_mvm_mac_wake_tx_queue

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.32% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 14a3aacf517a9de725dd3219dbbcf741e31763c4, 182d3c1385f44ba7c508bf5b1292a7fe96ad4e9e, 38d71acc15a2e72806b516380af0adb3830d4639.

Low priority for now. Upgrade to Linux Linux 14a3aacf517a9de725dd3219dbbcf741e31763c4, 182d3c1385f44ba7c508bf5b1292a7fe96ad4e9e, 38d71acc15a2e72806b516380af0adb3830d4639 or later.

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: fix double list_add at iwl_mvm_mac_wake_tx_queue After successfull station association, if station queues are disabled for some reason, the related lists are not emptied. So if some new element is added to the list in iwl_mvm_mac_wake_tx_queue, it can match with the old one and produce a BUG like this: [ 46.535263] list_add corruption. prev->next should be next (ffff94c1c318a360), but was 0000000000000000.
