UBUNTU-CVE-2023-34321

Arm provides multiple helpers to clean & invalidate the cache for a given region. This is, for instance, used when allocating guest memory to ensure any writes such as the ones during scrubbing have reached memory before handing over the page to a guest. Unfortunately, the arithmetics in the...

CVE-2023-46837 arm32: The cache may not be properly cleaned/invalidated (take two)

Arm provides multiple helpers to clean & invalidate the cache for a given region. This is, for instance, used when allocating guest memory to ensure any writes such as the ones during scrubbing have reached memory before handing over the page to a guest. Unfortunately, the arithmetics in the...

CVE-2023-46837

CVE-2023-46837 affects Xen on Arm. The vulnerability stems from overflow in cache-clean/invalidation helpers used during memory scrubbing, which can lead to undefined behavior and potential premature cache-write reordering, with no guarantee that writes reach memory before handing pages to guests...

CVE-2023-34326 x86/AMD: missing IOMMU TLB flushing

The caching invalidation guidelines from the AMD-Vi specification 48882—Rev 3.07-PUB—Oct 2022 is incorrect on some hardware, as devices will malfunction see stale DMA mappings if some fields of the DTE are updated but the IOMMU TLB is not flushed. Such stale DMA mappings can point to memory range...

CVE-2023-34326

CVE-2023-34326 concerns AMD-Vi (IOMMU) caching invalidation. The AMD-Vi specification guides improper invalidation: if DTE fields are updated but the IOMMU TLB is not flushed, devices may cause stale DMA mappings. These mappings can reference memory ranges not owned by the guest, potentially expo...

kernel: Linux kernel: Denial of Service in mlx5e due to incorrect encap attribute handling

A flaw was found in the mlx5e Traffic Control TC encapsulation logic in the net/mlx5e driver of the Linux kernel. The code responsible for invalidating encapsulation actions did not use the proper helper function to retrieve the correct encapsulation attribute, instead assuming the default...

kernel: filemap: Handle sibling entries in filemap_get_read_batch()

In the Linux kernel, the following vulnerability has been resolved: filemap: Handle sibling entries in filemapgetreadbatch If a read races with an invalidation followed by another read, it is possible for a folio to be replaced with a higher-order folio. If that happens, we'll see a sibling entry...
