CVE-2025-38532

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)
Description: A flaw was discovered in the Linux kernel’s libwx component related to the resetting of Rx ring descriptors. When a device reset is triggered by feature changes, such as toggling Rx VLAN offload, the wx->do reset() function is called to reinitialize Rx rings. However, the hardware descriptor ring may retain stale values from previous sessions, potentially leading to the construction of malformed SKBs.
Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
