CVE-2026-45981

A flaw was found in the Linux kernel, specifically within the s390/cio component. This vulnerability stems from incorrect device lifecycle management during subchannel allocation. This could allow an attacker to trigger use-after-free or double-free conditions, potentially leading to system...

CVE-2026-45981

In CVE-2026-45981, the Linux kernel s390/cio path css_alloc_subchannel() calls device_initialize() before configuring DMA masks. If dma_set_coherent_mask() or dma_set_mask() fails, the error path frees the subchannel directly, bypassing the device model reference counting. After device_initialize...

Joint Resource Optimization over Licensed and Unlicensed Spectrum in Spectrum Sharing UAV Networks against Jamming Attacks

Unmanned aerial vehicle UAV communication is of crucial importance in realizing heterogeneous practical wireless application scenarios. However, the densely populated users and diverse services with high data rate demands has triggered an increasing scarcity of UAV spectrum utilization. To tackle...
