Service interruption via partially initialized release state
Published Aug 10, 2026 · Updated Aug 10, 2026
Uninitialized pointer access in Linux kernel 6.10 through 7.1.5 allows local users to interrupt service during bnxt_en initialization. bnxt_aux_devices_init() registers an auxiliary device before fields consumed by bnxt_aux_dev_release() are populated, so allocation-failure cleanup dereferences or clears partial state. Reachability requires a Broadcom bnxt_en adapter with auxiliary devices and a later allocation failure; affected systems can become unstable or stop providing service.

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?
Compare these published version ranges with your installed build and any vendor patches.
