Valve Ships SteamOS 3.9.5 With eMudhra Certificate Revoked
The certificate revocation puts SteamOS on the same side as browsers that blocked eMudhra after the key compromise, and the timing gives Valve a security fix plus a power fix in the stable channel just before 4.0.
Reporting from 1 source: Game Spark.
Valve released SteamOS 3.9.5, the latest stable build for Steam Deck and other devices. The update revokes a compromised eMudhra CA certificate, moves desktop mode from KDE Plasma 6.4.3 to Plasma 6.7.3, and improves idle power draw on Steam Deck when audio is not playing. It also fixes bugs affecting Steam Machine performance. eMudhra, whose eight intermediate certificate private keys were compromised, has withdrawn from the global SSL/TLS certificate business as of October 22, 2026.
The revocation sits in the patch notes as a security and stability item. eMudhra, an India-based certificate authority, had the private keys of eight intermediate certificates compromised, a state in which malicious parties could more easily impersonate secure sites. The company has announced its withdrawal from the global SSL/TLS certificate business as of October 22, 2026.
The same build moves desktop mode from KDE Plasma 6.4.3 to Plasma 6.7.3, cuts idle power consumption on Steam Deck when audio is not playing, and fixes bugs that affected Steam Machine performance. Valve shipped it as version 3.9.5, the latest stable release in the SteamOS 3 line.
