Linux Kernel RDMA/hfi1 Memory Leak Vulnerability

A memory leak vulnerability has been identified in the Linux kernel's RDMA/hfi1 component. The issue arises in the setup_base_ctxt() function, which allocates memory for user context groups. If the init_user_ctxt() function fails, the allocated memory for the groups is not released, leading to a memory leak. The vulnerability affects several versions of the Linux kernel.

Impact

Exploitation of this vulnerability can lead to a memory leak, causing increased memory usage and potentially degrading system performance over time.

Remediation

Users can apply the latest patches available in the Linux kernel repository to address this vulnerability. Instructions for applying these patches can be found in the Linux kernel documentation.
