From The Linux Foundation

The LSB has two processes for reporting problems with the LSB: the formal process for requesting waivers to specification and test failures, and a more informal one for typical bug tracking, feature requests, and so on.

Formal Waiver Requests

Normally, any test failures would prevent certification of a product. When the failure is not caused by a defect in the product being tested, the Linux Foundation issues waivers to cover the problem. Waivers to failures are handled by the LSB Problem Reporting System. This process identifies failures from test journals which may require waivers; therefore, you must have a failure in a test journal to report a problem through this system. You will also need a regular Linux Foundation account.

LSB Bug Tracker

For tracking general bugs, feature requests, and release issues, the LSB maintains a Bugzilla instance. Note: bugzilla accounts are not linked to Linux Foundation website accounts yet, so you will need to set up a bugzilla account separately
