Description
A flaw was found in the Linux kernel's rtl8723bs wireless network driver. When handling wireless management frames under certain error conditions, the driver fails to release allocated transmission frames and buffers back to their memory pools. An attacker within radio range could send unexpected network traffic to trigger these error paths repeatedly, exhausting the driver's fixed transmission pool. This resource exhaustion prevents the network interface from sending essential wireless frames, resulting in a Denial of Service (DoS).
