CVE-2019-20423
Published: 27 January 2020
In the Lustre file system before 2.12.3, the ptlrpc module has a buffer overflow and panic due to the lack of validation for specific fields of packets sent by a client. The function target_handle_connect() mishandles a certain size value when a client connects to a server, because of an integer signedness error.
Notes
| Author | Note |
|---|---|
| sbeattie | lustre was removed from the upstream staging tree in 4.18 (be65f9ed267fd7d8b3146b7c4be9ecdd3e0aa3ed) |
| cascardo | The affected code was never part of linux, as the staging driver was only the client side. |
