Unspecified impact via out-of-bounds configuration access
Published Sep 24, 2026 · Updated Sep 24, 2026
Out-of-bounds access in the TC9563 PCI power-control driver in Linux 6.19 allows attackers to cause an unspecified impact via unspecified vectors. The probe logic parses both physical-function child nodes even though they share one configuration slot, so the second parse accesses beyond tc9563_pwrctrl->cfg. The condition requires a TC9563 DSP3 device-tree node exposing both functions; published material identifies neither an attacker-controlled path nor a concrete consequence.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
