CVE-2026-53133

The CVE-2026-53133 entry concerns the Linux kernel RDMA/umem component where an IOMMU-assisted mapping can split a very large block across multiple SG entries. During reassembly in __rdma_block_iter_next(), 32-bit stack values can overflow, causing incorrect DMA addresses for blocks at or beyond ...

CVE-2026-53124

A flaw was found in the ublk subsystem of the Linux kernel. When a ublk server fails to complete all I/O input/output operations, a per-I/O cancellation flag may remain set. This prevents the successful cancellation of outstanding I/O commands, potentially leading to resource exhaustion or a deni...
