  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7996: fix MLD ID in MAC TXD and HIF TXP\n\nProblem:\nMCU command timeout while the firmware state is normal, and the\nfirmware keeps showing the error log \"ERROR!! NO PAUSE...\".\n\nRoot cause:\nIf the MLD_ID field in the TXD is neither the primary link id nor the\nsecondary link id, it may lead to a firmware busy loop when the third\nlink is in power saving mode.\n\nRemap frames directed to a third link to the primary link wcid. Since\nTX status events and txfree completions carry the wcid the firmware\nsaw, use the remapped wcid for packet id tracking and non-AQL packet\naccounting as well, while the frame keeps its original link context\nfor addressing, band and OMAC selection.",
