UBUNTU-CVE-2026-98731: Medium severity ubuntu/linux-hwe-edge vulnerability
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintelpcie: fix plen overflow in btintelpcierecvframe() plen is u16 and computed as HDRSIZE + 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 skbtrim() truncate the packet. Widen plen to u32 so the addition cannot wrap.

Recommended actions to resolve this vulnerability, in priority order.
- Compensating control
In btintel_pcie_recv_frame(), widen plen from u16 to u32 so the HDR_SIZE + dlen addition cannot wrap.
