In the Linux kernel, the following vulnerability has been resolved: drm/virtio: fix dmafence refcount leak on error in virtiogpudmafencewait dmafenceunwrapforeach internally calls dmafenceunwrapfirst which does cursor-chain = dmafencegethead, taking an extra reference. On normal loop completion,...

CVE-2026-53190

CVE-2026-53190 concerns a Linux kernel vulnerability in the drm/virtio path where a refcount leak could occur in error handling of virtio_gpu_dma_fence_wait(). The root cause is that dma_fence_unwrap_for_each() calls dma_fence_unwrap_first(), which assigns cursor->chain = dma_fence_get(head) (...

CVE-2026-53171

The CVE affects the Linux kernel’s accel/ethosu driver. The dma_length() function can under- or overflow while deriving DMA region usage, causing region_size[] to be under-reported and potentially bypassing bounds checks in ethosu_job.c. The issue arises from arithmetic in len calculations, signe...

CVE-2026-53170

Concrete details confirm a vulnerability in the Linux kernel accel/ethosu driver: cmd_state_init() leaves dma->len at U64_MAX to signal uninitialized length, and dma_length() can wrap a positive stride to a small value, causing a bypass of region checks in ethosu_job.c when userspace omits the...

CVE-2026-53164 iommu/dma: Do not try to iommu_map a 0 length region in swiotlb

In the Linux kernel, the following vulnerability has been resolved: iommu/dma: Do not try to iommumap a 0 length region in swiotlb iommudmaiovalinkswiotlb processes a mapping that is unaligned in three parts, the head, middle and trailer. If the middle is empty because there are no aligned pages ...
