CVE-2025-38392

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.15.0-rc5+

Description A flaw exists in the Linux kernel related to the idpf (Intel Data Plane Framework) driver. Specifically, a mutex used for the control queue (cq lock) can lead to a kernel BUG when VIRTCHNL2 CAP MACFILTER is enabled. This occurs due to a potential deadlock situation during DMA memory freeing, which may utilize vunmap(). The issue arises from the interaction between the mutex lock and spinlock operations within the idpf ctlq clean sq() function, triggered through a sequence of function calls initiated by rtnl newlink().

Recommendations Update to a version of the Linux kernel that includes the fix for this issue.
