CVE-2019-20427
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.90%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
