FKIE_CVE-2025-38151

Vulnerability from fkie_nvd - Published: 2025-07-03 09:15 - Updated: 2025-12-18 21:07
Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: RDMA/cma: Fix hang when cma_netevent_callback fails to queue_work The cited commit fixed a crash when cma_netevent_callback was called for a cma_id while work on that id from a previous call had not yet started. The work item was re-initialized in the second call, which corrupted the work item currently in the work queue. However, it left a problem when queue_work fails (because the item is still pending in the work queue from a previous call). In this case, cma_id_put (which is called in the work handler) is therefore not called. This results in a userspace process hang (zombie process). Fix this by calling cma_id_put() if queue_work fails.
