Hey Community,
Sophos is investigating a few reported occasions of a BSOD - UNEXPECTED_KERNEL_MODE_TRAP (7f) on computers running one of the SafeGuard File Encryption modules e.g. File Encryption, Synchronized Encryption, Data Exchange, Cloud Storage. The BSOD occurs after the update to the latest Windows 10 feature release version 1803 (build 17134).
The issue only affects a small subset of computers and is not yet reproducible internally. On affected systems it apparently only occurs, when logging on with a domain account.
Based on a first analysis, the reason is a stack overflow caused by a kernel function. The involvement of SafeGuard is yet unclear.
Please follow this Advisory KBA for more information and updates as they become available.
Regards,
