CVE-2026-74713

CVE-2026-74713 affects the Linux kernel vhost_iotlb subsystem. The root cause is that vhost_iotlb_add_range_ctx() only retires an old entry when the table has a non-zero limit, has exactly reached that limit, and has VHOST_IOTLB_FLAG_RETIRE set. Non-retiring tables can keep allocating entries aft...

CVE-2026-74712

CVE-2026-74712 is a slab-out-of-bounds read in the Linux kernel mlx5_vdpa driver, specifically in the create_direct_keys() function. The root cause is a size calculation mismatch: the input buffer length passed to cmd_exec includes the full structure size (out + in + mtt[]), but the pointer point...

CVE-2026-74710

CVE-2026-74710 is a vulnerability in the Linux kernel's AF_XDP (xsk) subsystem . The kernel accepted a TX metadata length as small as 8 bytes , but every supported request requires flags plus at least one 8-byte request field. This insufficient validation allowed the kernel to read beyond the reg...
