CVE-2026-74573

Concise summary: CVE-2026-74573 affects the Linux kernel IOMMU arm-smmu-v3-iommufd. The vulnerability arises when a vDEVICE is mapped to more than one stream: arm_vsmmu_vsid_to_sid() uses only master->streams[0], so guests with multiple streams may not invalidate all ATC/IOTLB entries; if ther...

CVE-2026-74573 iommu/arm-smmu-v3-iommufd: Require exactly one Stream ID for a vDEVICE

In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu-v3-iommufd: Require exactly one Stream ID for a vDEVICE armvsmmuvsidtosid maps a guest's vSID to a single physical Stream ID taken from master-streams0, assuming a device has exactly one stream. A device with sever...

CVE-2026-74444

The vulnerability CVE-2026-74444 affects the Linux kernel DRM vmwgfx driver. In vmw_cmd_draw, the header size from user input can cause an unsigned subtraction (header->size - sizeof(cmd->body)) to wrap to ~4 GiB when header->size is undersized, leading to a large maxnum and an out-of-bo...

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: bound DMA command body size against suffix pointer vmwcmddma locates the DMA suffix at unsigned long &cmd-body + header-size - sizeofsuffix without checking that header-size is large enough to contain both cmd-body an...

CVE-2026-72445

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: qcom: clear opened when stream enable fails On enable, subs-opened is set before the serviceinterval is validated; an invalid interval jumps to the response label without clearing it, so the substream is wedged a...

CVE-2026-72251

CVE-2026-72251 concerns the Linux kernel netfilter nf_nat_sip path. The issue is a memory-pointer/buffer handling flaw: if skb_ensure_writable() reallocates a cloned/fragmented skb, nf_nat_sip() may not update the destination pointer (dptr ) to the new buffer, risking a stale data pointer and pot...
