description

The Linux kernel RDS over InfiniBand component can retain a stale scatterlist pointer after a memory-region mapping failure. A local attacker may be able to trigger later use of the freed memory and escalate privileges; exploitation depends on reaching the affected RDS/InfiniBand memory-region handling path.

mitigation

Update to a kernel build containing one of the listed fixed revisions, including 1be3211e6ac77adbb1eac01314d989d243b32c59. Until updated, reduce exposure by disabling or restricting access to RDS over InfiniBand where it is not required.
