CVE-2026-45944

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Clear Present bit before tearing down context entry When tearing down a context entry, the current implementation zeros the entire 128-bit entry using multiple 64-bit writes. This creates a window where the hardware c...

CVE-2026-46052

The CVE-2026-46052 issue concerns the Linux kernel Ceph filesystem where a negative dentry that is already hashed can be re-added to the dcache, corrupting the d_hash bucket and leading to an RCU stall or system hang. The root cause is that d_add() can rehash and reinstate a dentry that is alread...

CVE-2026-45945 iommu/vt-d: Fix race condition during PASID entry replacement

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Fix race condition during PASID entry replacement The Intel VT-d PASID table entry is 512 bits 64 bytes. When replacing an active PASID entry e.g., during domain replacement, the current implementation calculates a ne...

CVE-2026-45945

The CVE-2026-45945 vulnerability affects the Linux kernel iommu/vt-d PASID entry handling. A race condition arises when replacing an active 512-bit PASID table entry; the existing approach writes a new entry in place, risking torn reads if the hardware fetches the entry in multiple 128-bit chunks...

CVE-2026-45944

CVE-2026-45944 affects the Linux kernel IOMMU VT-d. During context-entry teardown, the implementation zeros a 128‑bit entry in two 64‑bit writes, risking a torn entry where the Present bit remains set while other fields are zeroed, potentially causing unpredictable behavior or spurious faults. Th...
