From: Greg Kroah-Hartman Description =========== 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. The Linux kernel CVE team has assigned CVE-2026-99094 to this issue. Affected and fixed versions =========================== Issue introduced in 6.10 with commit 6e65a09f927566f2
