CVE-2026-64152
In the Linux kernel, the following vulnerability has been resolved: iommu: Handle unmap error when iommudebug is enabled Sashiko noticed a latent bug where the map error flow called iommuunmap which calls iommudebugunmapbegin/iommudebugunmapend however since this is an error path the map flow nev...
CVE-2026-64152
CVE-2026-64152 affects the Linux kernel iommu path. The issue arises when an unmap error in the iommu_debug flow occurs in an error path that did not establish the original iommu_debug_map, causing mis-tracing and unbalanced tracking. Fix: move the unmap error handling into iommu_map_nosync() and...

In the Linux kernel, the following vulnerability has been resolved: dma-mapping: move dmamapresource sanity check into debug code dmamapresource uses pfnvalid to ensure the range is not RAM. However, pfnvalid only checks for availability of the memory map for a PFN but it does not ensure that the...
CVE-2026-64149
In the Linux kernel, CVE-2026-64149 fixes a DMA mapping sanity check: dma_map_resource() previously relied on pfn_valid() to exclude RAM, but this could misclassify MMIO regions sharing a sparsemem section as usable RAM, triggering a WARN_ON_ONCE and DMA_MAPPING_ERROR on platforms like Raspberry ...

In the Linux kernel, the following vulnerability has been resolved: mm/pagealloc: fix initialization of tags of the huge zero folio with initonfree GFPZEROTAGS semantics are currently a bit weird, but effectively this flag is only ever set alongside GFPZERO and GFPSKIPKASAN. If we run with...
CVE-2026-64072 nvme: fix bio leak on mapping failure
In the Linux kernel, the following vulnerability has been resolved: nvme: fix bio leak on mapping failure The local bio is always NULL, so we'd leak the bio if the integrity mapping failed. Just get it directly from the request...
CVE-2026-64072
The CVE-2026-64072 vulnerability affects the Linux kernel, specifically the NVMe I/O path. It describes a fix for a bio leak that occurred when an integrity mapping failed during mapping; the code could leak a local bio because it was treated as NULL. The root cause is that the kernel attempted t...

CVE-2026-64051 accel/qaic: Add overflow check to remap_pfn_range during mmap
In the Linux kernel, the following vulnerability has been resolved: accel/qaic: Add overflow check to remappfnrange during mmap The call to remappfnrange in qaicgemobjectmmap is susceptible to remapping beyond the VMA if the BO is too large. This can cause use after free issues when munmap unmaps...

CVE-2026-63952 memfd: deny writeable mappings when implying SEAL_WRITE
In the Linux kernel, the following vulnerability has been resolved: memfd: deny writeable mappings when implying SEALWRITE When SEALEXEC is added, SEALWRITE is implied to make W^X. But the implied seal is set after the check that makes sure the memfd can not have any writable mappings. This means...

CVE-2026-63950
Summary: CVE-2026-63950 pertains to the Linux kernel mm/rmap path. The issue arose from not reinitializing nr_pages at the start of each loop in try_to_unmap_one, allowing a value from a previous folio_unmap_pte_batch() to be reused in a later iteration. This could cause corruption of folio refco...
