Local denial of service via recursive team locking
Published Mar 6, 2025 · Updated May 12, 2026
Improper locking in Linux since 3.3 and all Siemens SIMATIC S7-1500 TM MFP GNU/Linux subsystem versions allows local users to hang the kernel. The team_add_slave path accepts a device already beneath an existing team port, and the resulting device event reacquires team_lock while that mutex is already held. Exploitation requires local access with network-link administration rights; the resulting recursive lock can leave the system unavailable.

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.
