CVE-2026-46140

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Bluetooth: btmtk: validate WMT event SKB length before struct access<br /> <br /> btmtk_usb_hci_wmt_sync() casts the WMT event response SKB data to<br /> struct btmtk_hci_wmt_evt (7 bytes) and struct btmtk_hci_wmt_evt_funcc<br /> (9 bytes) without first checking that the SKB contains enough data.<br /> A short firmware response causes out-of-bounds reads from SKB tailroom.<br /> <br /> Use skb_pull_data() to validate and advance past the base WMT event<br /> header. For the FUNC_CTRL case, pull the additional status field bytes<br /> before accessing them.
