Overview
CVE-2026-98731 is a known-severity vulnerability. It was published on October 18, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btintel_pcie: fix plen overflow in btintel_pcie_recv_frame()
plen is u16 and computed as HDR_SIZE + dlen. For ACL/ISO frames dlen
is a 16-bit field, so a value >= 0xFFFC wraps the sum, bypassing the
"skb->len < plen" check and letting skb_trim() truncate the packet.
Widen plen to u32 so the addition cannot wrap.
