CVE-2025-38532 is a vulnerability in the Linux kernel's libwx network driver where the Rx ring descriptor is not properly reset during device reset triggered by feature changes such as toggling Rx VLAN offload. This can cause the hardware descriptor ring to retain stale values, leading to malformed socket buffers (SKBs) and kernel crashes (BUG). The issue has been resolved by ensuring the Rx ring descriptors are fully reset after device reset.
