Description

A flaw was found in the Linux kernel's pseries/papr-hvpipe component. A local user could trigger a null pointer dereference in the papr_hvpipe_dev_create_handle() function. This occurs when src_info is improperly re-used after being nulled, leading to a kernel panic. This vulnerability could result in a Denial of Service (DoS) for the affected system.
