Adjacent-network code execution via SMB use-after-free
Published Apr 23, 2025 · Updated Apr 23, 2025
Use-after-free in libsmb2 on Sonos Era 300 version 81.1-58074 allows attackers to execute code through crafted SMB data. The SMB-processing path fails to verify that an object still exists before operating on it, causing libsmb2 to access freed memory. Attackers need adjacent-network access, but no authentication or user interaction, and successful exploitation runs code as the anacapa user.

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.
