Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from lustre. Update lustre to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
