CVE-2021-47064

CVE-2021-47064 concerns the Linux kernel mt76 wireless driver. The issue arises in the mt76_dma_tx_queue_skb_raw path where buf can be uninitialized, causing the field skip_unmap to inherit a non-zero value from stack garbage. As a result, DMA mappings for MCU command frames may not be unmapped a...

CVE-2023-52490

The CVE-2023-52490 issue is a Linux kernel mm/migrate flaw where a race in page migration caused an incorrect page mapping for the target page, leading to NULL dereferences during dump of page state when memory hotplug/offlining occurs. The root cause was that the target page’s mapping field stor...
