Title
wifi: mt76: mt7996: use hweight16 to get correct tx antenna
Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: use hweight16 to get correct tx antenna The chainmask is u16 so using hweight8 cannot get correct tx_ant. Without this patch, the tx_ant of band 2 would be -1 and lead to the following issue: BUG: KASAN: stack-out-of-bounds in mt7996_mcu_add_sta+0x12e0/0x16e0 [mt7996e]
Severity
7.6 (High)

              "value": "AV:A - The vulnerable path is entered from mac80211 station insertion driven by an over-the-air association from a nearby 802.11 peer, with the trigger conditions (EHT/HE/VHT beamforming capability bits, bandwidth, MCS/NSS fields) taken straight from the attacker\u0027s association request. This requires radio proximity to the AP\u0027s 6 GHz band rather than routable network access, which is Adjacent per the WiFi frame-injection guidance.\nAC:L - On the affected hardware the miscount is deterministic \u2014 band 2\u0027s chainmask sits entirely above bit 7, so hweight8() always returns 0 and tx_ant is always -1 \u2014 and the attacker simply associates while advertising SU-beamformee support to reach matrix[-1][ncol] every time. There is no race, no memory-layout requirement, and the attempt can be repeated indefinitely by re-associating.\nPR:N - In AP mode hostapd creates the station object at association, before the 4-way handshake or any credential validation, so mt7996_mac_sta_add() \u2192 mt7996_mcu_sta_bfer_tlv() runs for an attacker holding no key and no account on the target. Open and mesh/IBSS deployments have no authentication gate at all.\nUI:N - The attacker performs the association itself and the AP\u0027s kernel processes it automatically; no action by any user or administrator on the victim system is needed.\nS:U - The out-of-bounds read and the resulting bogus firmware-command fields stay within the kernel driver\u0027s own security authority, crossing no VM, IOMMU, or sandbox boundary.\nC:L - matrix[-1][ncol] reads adjacent kernel stack memory outside the const array, exposing stack contents that are then written into the sta_rec_bf TLV and transmitted to the WiFi firmware. The read is strictly bounded to the four bytes immediately preceding a 16-byte object at a fixed negative offset with no attacker-directed address and no channel returning the data over the air, so it is a small bounded leak rather than arbitrary read.\nI:L - The uninitialized out-of-bounds byte and the underflowed antenna count (ibf_nrow = 0xFF, mem_20m/mem_total derived from stray stack data) are programmed into the chip\u0027s beamforming profile via the MCU STA_REC_UPDATE command, a remotely-influenced corruption of device configuration state. No kernel memory is written out of bounds and no control-flow influence is available, so the modification is limited rather than arbitrary.\nA:H - The condition is a KASAN-detected stack-out-of-bounds in mt7996_mcu_add_sta(), which oopses and panics outright on kernels built with KASAN plus panic_on_warn or kasan.fault=panic \u2014 common in vendor and hardened builds. Independently, feeding out-of-range beamforming memory parameters and a 0xFF antenna count to the WiFi MCU can wedge the firmware and take the radio down, and the attacker can retrigger it on every association."
