Lifecycle Timeline
1DescriptionNVD
In the Linux kernel, the following vulnerability has been resolved:
RDMA/hns: Fix cpu stuck caused by printings during reset
During reset, cmd to destroy resources such as qp, cq, and mr may fail, and error logs will be printed. When a large number of resources are destroyed, there will be lots of printings, and it may lead to a cpu stuck.
Delete some unnecessary printings and replace other printing functions in these paths with the ratelimited version.
AnalysisAI
In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix cpu stuck caused by printings during reset During reset, cmd to destroy resources such as qp, cq, and mr may fail,. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity. This Allocation of Resources Without Limits vulnerability could allow attackers to exhaust system resources through uncontrolled allocation.
Technical ContextAI
This vulnerability is classified as Allocation of Resources Without Limits (CWE-770), which allows attackers to exhaust system resources through uncontrolled allocation. In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix cpu stuck caused by printings during reset During reset, cmd to destroy resources such as qp, cq, and mr may fail, and error logs will be printed. When a large number of resources are destroyed, there will be lots of printings, and it may lead to a cpu stuck. Delete some unnecessary printings and replace other printing functions in these paths with the ratelimited version. Affected products include: Linux Linux Kernel.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Set resource limits, implement rate limiting, validate input sizes.
