CVE-2026-98392: Bluetooth: btintel_pcie: fix tx_handle bounds off-by-one

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: 0.20% (FIRST EPSS).
  • Fixed version: Linux Linux 3dd1b41f96aad08444be1b7626c89de2b9f2abd4, 72bbd7c815ef92399b7b109977ae4669ce22ee6e, 932a87444107e6724d808082676bba5c915c98ad.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 3dd1b41f96aad08444be1b7626c89de2b9f2abd4, 72bbd7c815ef92399b7b109977ae4669ce22ee6e, 932a87444107e6724d808082676bba5c915c98ad or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintel_pcie: fix tx_handle bounds off-by-one Valid indices into txq->urbd0s/tfds/bufs are 0..txq->count-1, so tfd_index == txq->count is already out of range. Change the guard in btintel_pcie_msix_tx_handle() from '> txq->count' to '>= txq->count'. This issue was reported by Claude Mythos.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
