CVE-2026-45890

The CVE-2026-45890 issue affects the Linux kernel Xen-netback. A Xen guest can set multi-queue-num-queues to 0; the connect() validation checks only the upper bound (requested_num_queues > xenvif_max_queues) and does not reject zero. This can reach vzalloc(array_size(0, sizeof(struct xenvif_qu...

kernel: Linux kernel: integer overflow and information disclosure via undefined shift operation in drm/amdkfd

A flaw was found in the Linux kernel’s AMD Kernel Fusion Driver amdkfd within the drm subsystem. When either getnumsdmaqueues or getnumxgmisdmaqueues returned 0, the driver performed a bit shift where the number of bits shifted equaled the operand width. Such a shift is undefined behavior in C an...
