linux — security advisory
In the Linux kernel, the following vulnerability has been resolved: irqchip/gicv3: Workaround for NVIDIA erratum T241-FABRIC-4 The T241 platform suffers from the T241-FABRIC-4 erratum which causes unexpected behavior in the GIC when multiple transactions are received simultaneously from different sources. This hardware issue impacts NVIDIA server platforms that use more than two T241 chips interconnected. Each chip has support for 320 {E}SPIs. This issue occurs when multiple packets from different GICs are incorrectly interleaved at the target chip. The erratum text below specifies exactly what can cause multiple transfer packets susceptible to interleaving and GIC state corruption. GIC state corruption can lead to a range of problems, including kernel panics, and unexpected behavior. >From the erratum text: "In some cases, inter-socket AXI4 Stream packets with multiple transfers, may be interleaved by the fabric when presented to ARM Generic Interrupt Controller. GIC expects all transfers of a packet to be delivered without any interleaving. The following GICv3 commands may result in multiple transfer packets over inter-socket AXI4 Stream interface: - Register reads from GICD_I* and GICD_N* - Register writes to 64-bit GICD registers other than GICD_IROUTERn* - ITS command MOVALL Multiple commands in GICv4+ utilize multiple transfer packets, including VMOVP, VMOVI, VMAPP, and 64-bit register accesses."
