CVE-2026-93830

A flaw was found in the Linux kernel's stmmac network driver. An attacker can cause a Denial of Service DoS by sending high volumes of network traffic to an affected system. Under heavy packet load, the network controller exhausts its receive buffers and continuously fires hardware interrupts...

CVE-2026-97515

A flaw was found in the Linux kernel's I3C Improved Inter-Integrated Circuit master driver. On affected hardware, when a target device on the bus holds the data line low, the controller triggers an interrupt feedback loop during recovery attempts. This issue creates an interrupt storm that can...

CVE-2026-93830

The Linux kernel contains a vulnerability where enabling the RX Buffer Unavailable (RBUE) interrupt in the xgmac2 driver can trigger a MAC interrupt storm under heavy RX pressure. This occurs because the DMA fires RBUE continuously when it runs out of RX descriptors, while the standard RX complet...
