CVE-2019-20427
Published: 27 January 2020
In the Lustre file system before 2.12.3, the ptlrpc module has a buffer overflow and panic, and possibly remote code execution, due to the lack of validation for specific fields of packets sent by a client. Interaction between req_capsule_get_size and tgt_brw_write leads to a tgt_shortio2pages 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. |
