      "title": "wifi: iwlwifi: mvm: fix driver-set TX rates on old devices",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: iwlwifi: mvm: fix driver-set TX rates on old devices\n\nOn old devices such as 7265D, rates are still encoded in version 1\nformat, which doesn't use the CCK/OFDM rate index (0-3/0-7) but\nrather their PLCP value (e.g. 10 for 1 Mbps CCK rate.)\n\nWhile introducing v3 rates, I changed the driver from internally\nhandling v1 rates and converting to v2, to internally handling v3\nand converting to v1 or v2 according to the firmware. I accordingly\nchanged the code in iwl_mvm_mac80211_idx_to_hwrate() to no longer\nhave different values for different APIs. This was correct.\n\nHowever, I later reverted this part of the change, because it was\nreported that I had broken beacon rates, causing a FW assert/crash.\nThis caused TX_CMD rates to be set incorrectly, potentially causing\na warning when reported back from the device as having been used.\n\nFix this (hopefully correctly now) by handling beacon rates in the\nTX_CMD that's embedded in the beacon template command separately.\nRestore iwl_mvm_mac80211_idx_to_hwrate() to return only the rate\nindex, not PLCP value, fixing the real TX_CMD.",
