FreeBSD-EN-21:14.pms : pms(4) data corruption
Versions Affected : All versions prior to TrueNAS 12.0-U4
Two problems are fixed by this update. First, the pms(4) driver did not correctly handle the new kern.maxphys value set in FreeBSD 13.0. Second, the pms(4) driver did not correctly handle some error cases in the I/O path and would falsely report success to upper layers.
The bugs may cause data corruption.
No workaround is available. Systems not using pms(4) are unaffected.
- Upgrade to TrueNAS 12.0-U4 or later.
