This month's fixes were shared with Android partners on January 4. However, so far the only vendor to have patched the issue is BlackBerry, which released an update for PRIV Android handsets within 24 hours of Google's over-the-air update for Nexus handsets on Monday.
Google also addressed a pair of equally serious bugs in the Broadcom Wi-Fi driver that allow an attacker on the same Wi-Fi network to corrupt kernel memory.
"Multiple remote execution vulnerabilities in the Broadcom Wi-Fi driver could allow a remote attacker to use specially-crafted wireless control message packets to corrupt kernel memory in a way that leads to remote code execution in the context of the kernel," Google notes.
Overall, the February update addresses 13 security bugs, of which seven are critical, four high severity, and two moderate.
The fixes bring Google's Android Security Patch Level up to February 1, 2016, which Android OEMs such as Samsung, LG, Sony, and others should be rolling in the coming month at least to flagship handsets.
