CVE-2026-98731: Bluetooth: btintel_pcie: fix plen overflow in btintel_pcie_recv_frame()

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.21% (FIRST EPSS).
  • Fixed version: Linux Linux 7dbeb6935ac331b0cba6c41cabd8e9d02d5f64ea, b2cb5ea1dc8cf829816370fc1399e6a1d2d1bca9, c3a3842c109ac130c6db3aa0014cc8cd344928ad.

Low priority for now. Upgrade to Linux Linux 7dbeb6935ac331b0cba6c41cabd8e9d02d5f64ea, b2cb5ea1dc8cf829816370fc1399e6a1d2d1bca9, c3a3842c109ac130c6db3aa0014cc8cd344928ad or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
