- Details
-
In the Linux kernel, the following vulnerability has been resolved:
RDMA/hns: Fix log flood after cmd_mbox failure
hnsrocecmdmbox() is the command interface between driver and hardware. When hardware is abnormal, the unlimited error printings after hnsrocecmdmbox() failure will cause log flood and even system crash.
Replace ibdeverr() and ibdevwarn() with their ratelimited versions in the error handling path after hnsrocecmdmbox() (and its wrappers hnsrocecreatehwctx/hnsrocedestroyhw_ctx) fails.
