Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

In the Lustre file system before 2.12.3, the ptlrpc module has an out-of-bounds access and panic due to the lack of validation for specific fields of packets sent by a client. In the function lustre_msg_string, there is no validation of a certain length value derived from lustre_msg_buflen_v2.
