The Linux Vendor Firmware Service (LVFS) that integrates with Fwupd for delivering firmware updates primarily to Linux users is surging with around three times the normal traffic volume. Unfortunately, this boost in traffic appears to be due to vendor(s) releasing new system firmware updates ahead of disclosing a presumptive security issue.

Last summer LVFS shot up with activity and when that huge uptick in LVFS activity occurred it ended up being due to Dell BIOS/UEFI updates due to new security vulnerabilities.

The sudden surge in LVFS/Fwupd activity at around three times its usual volume does seem to point to another imminent security vulnerability being disclosed around system firmware.
