CVE-2026-23390

CVE-2026-23390 : In the Linux kernel, the tracing/dma subsystem fixes a potential perf buffer overflow in the dma_map_sg tracepoint when handling large scatter-gather lists (e.g., large DRM buffers). The patch caps the three dynamic arrays at 128 entries using min() to prevent excessive allocatio...

CVE-2026-23174

The CVE-2026-23174 entry concerns the Linux kernel nvme-pci subsystem. Root cause: dma_needs_unmap may switch from false to true during data-iterator mapping, and the nvme driver must preserve mapped DMA vectors for later unmapping. The fix is to allocate/unprepare storage for DMA vectors on dema...

CVE-2026-23093

Summary (CVE-2026-23093) : In the Linux kernel, the ksmbd: smbd DMA unmapping path uses dma_unmap_sg() with a different number of entries than dma_map_sg(), which is the root cause of the vulnerability. The fix ensures dma_unmap_sg() is called with the same nents as dma_map_sg(). According to the...
