A flaw was found in the way Linux kernel’s Dynamic Logical Partitioning (DLPAR) functionality on PowerPC systems handled low memory conditions on device discovery. An attacker who can change the LPAR configuration and incur low memory conditions at the same time could use this flaw to crash the system.
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
