Home Assistant OS 17.3

[sairon]

Changes

Home Assistant Operating System 17.3 is a security release that only updates the Linux kernel to the latest version. For Raspberry Pi targets, the relevant algif_aead fixes for CVE-2026-31431 (Copy Fail) have been explicitly backported.

Note

In practice, most parts of a Home Assistant Operating System installation are not meaningfully affected by this vulnerability: Home Assistant Operating System is a single-application appliance, and Home Assistant's security model expects that logged-in users are trusted and does not rely on separating trusted local users from each other. Most parts (including Home Assistant Core and custom components) already run as root. Fixing this CVE only meaningfully improves the security posture for apps (formerly add-ons) that intentionally drop privileges (apps running as a non-root user).

Home Assistant Green with Connect ZBT-2 successfully updated from 17.2 to 17.3. Everything running OK.

All good bare-metal NUC: no installation or startup issues with ZBT-1,2 and ZWA-2

Also good on RPi4.

Tried to update from 17.2, but it disconnects in the middle of it and won’t reconnect. Reboot and try again, same thing. I’m a newb though :(

Hey, you guys, you’re doing a great job

Yellow (no NVMe) 17.2 -> 17.3. Everything fine.

Has the Raspberry problems of revision 17.2 been fixed with revision 17.3?

[illright]

Raspberry Pi 4B — not successful. Stopped responding after I launched the update

[illright]

Power cycled the Pi, then it booted

There is a CPU usage peak that appeared after the latest upgrade.
Happened two times, at 00:00 each time.

UPD: This is Music Assistant Beta #10

Generic x86-64 here. Finish installation, reboots e and still shows the same update to do. I guess it's failing.

[cavazos-apps]

Another x86-64 here unable to update to 17.3

[cavazos-apps]

Full power cycle of the VM appeared to resolve the inability to update.

Using RPi5 and NVME this update (17.1 -> 17.3) fried my setup. Multiple hard-resets without success.
