CVE-2026-74265

The CVE describes a Linux kernel fix in net: mana where gdma queue id is now initialized to INVALID_QUEUE_ID immediately after allocation. Previously, mana_gd_create_mana_wq_cq() left queue->id as 0 until mana_create_wq_obj() set the firmware-returned id; if creation failed before that, cleanu...

CVE-2026-72064 net: mana: Sync page pool RX frags for CPU

In the Linux kernel, the following vulnerability has been resolved: net: mana: Sync page pool RX frags for CPU MANA allocates RX buffers from page pool fragments when fragcount is greater than 1. In that case the buffers remain DMA mapped by page pool and the RX completion path does not call...

CVE-2026-72065

The CVE-2026-72065 issue affects the Linux kernel networking path for mana devices: it fixes a vulnerability where the packet length reported by the NIC RX CQE could be unchecked before skb processing. The underlying problem is trusting CQE-reported lengths from the NIC and passing them to skb ha...

CVE-2026-72064

CVE-2026-72064 relates to the Linux kernel net: mana RX path. When frag_count > 1, RX buffers are allocated from page pool fragments and remain DMA mapped; the RX completion path omits dma_unmap_single(), so the implicit CPU sync is not performed before passing data to the networking stack. Th...

CVE-2026-64018

A flaw was found in the Linux kernel's mana network driver. In Confidential Virtual Machines VMs, a missing bounds check when processing network events can allow a malicious hardware component or a compromised VM to write data outside of an intended memory region. This out-of-bounds access could...
