Summary

The Linux kernel from 2.6.14 is affected in its libipw wireless driver. The Michael MIC verifier assumes every TKIP frame carries an eight-byte MIC, so a short frame makes the unsigned payload length wrap and the MIC computation reads past the buffer. The fix checks that the MIC is present before verifying it.

Description from the CNA

In the Linux kernel, the following vulnerability has been resolved: wifi: libipw: reject TKIP frames without a full MIC libipw_michael_mic_verify() assumes that an skb contains an eight-byte Michael MIC. A short TKIP frame makes the unsigned payload length wrap, causing michael_mic() to read past the skb. Check that the MIC is present before verifying it, and use the existing MICHAEL_MIC_LEN constant for all MIC lengths in the verifier.
