High

Base vector

AV:N/AC:L/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions Lustre file system versions prior to 2.12.3

Description The issue is related to the ptlrpc module in the Lustre file system, where a lack of validation for specific fields of packets sent by a client can lead to an out-of-bounds access and panic. Specifically, the function lustre msg string does not validate a certain length value derived from lustre msg buflen v2. This can be exploited by a remote attacker to cause a denial of service.

Recommendations For versions prior to 2.12.3, update to version 2.12.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the ptlrpc module to minimize the risk of exploitation.
