CVE-2025-38132

Estado: AnalizadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

coresight: holding cscfg_csdev_lock while removing cscfg from csdev

There'll be possible race scenario for coresight config:

iterating config_csdev_list could be raced with config_csdev_list's entry delete.

To resolve this race , hold csdev->cscfg_csdev_lock() while cscfg_remove_owned_csdev_configs()
