CVE-2024-47714 Details
Description
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]
A stack-out-of-bounds vulnerability has been identified in the Linux kernel's MediaTek Wi-Fi 7 (802.11be) driver, specifically in the mt7996 component. This issue arises from the incorrect handling of the transmission antenna data due to a mismatch in data size. The vulnerability is present in the stable versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been patched. The specific commit addressing this issue is available in the Linux kernel stable tree.
