CVE-2025-38024:
Linux Kernel vulnerability analysis and mitigation
Overview
CVE-2025-38024 is a vulnerability in the Linux kernel related to a slab-use-after-free issue in the RDMA/rxe subsystem, specifically in the rxequeuecleanup function. The vulnerability was published on June 18, 2025, and affects the Linux kernel's Remote Direct Memory Access (RDMA) softRoCE implementation (NVD).
Technical details
The vulnerability occurs in the rxecreatecq function when rxecqfrominit fails. The issue arises because some memory resources are prematurely freed in the rxecqfrominit function before rxecleanup is called to handle the allocated resources. This leads to a use-after-free condition in the rxequeuecleanup function. The vulnerability manifests in the drivers/infiniband/sw/rxe/rxequeue.c file at line 195 (NVD).
Impact
A successful exploitation of this vulnerability could lead to system instability or potential privilege escalation due to the use-after-free condition in kernel memory management. The issue affects the kernel's RDMA subsystem, which is critical for high-performance networking applications (NVD).
Mitigation and workarounds
The solution involves modifying the cleanup process to ensure that rxe_cleanup handles all resource deallocation properly, preventing the premature freeing of memory resources. The fix has been implemented in the Linux kernel (NVD).
