Summary

The btintel_pcie Bluetooth driver in the Linux kernel from 6.10 uses a TX descriptor index before the bounds check, so an index equal to the queue count passes and reaches one past the end of both arrays. An adjacent attacker without privileges or user interaction can affect confidentiality, integrity and availability, though the attack is highly complex.

Description from the CNA

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintel_pcie: fix TX descriptor bounds check btintel_pcie_prepare_tx() uses tfd_index to access the TFD and data buffer arrays before the index is advanced modulo txq->count. An index equal to txq->count is one past the end of both arrays, so reject it in the bounds check.
