CVE-2026-23063

CVE-2026-23063 pertains to the Linux kernel, specifically the UACCE accelerator framework. The issue arises in the queue release path for uacce_queue when resources could be freed concurrently (e.g., during poweroff -f with accelerators still active). The root cause is unsafe sequencing of operat...

CVE-2026-23056

The CVE concerns the Linux kernel uacce driver: the vm_operations_struct.mremap operation is not implemented, and the fix disables mremap by implementing .mremap to return -EPERM. Without this, the default mremap could replay a vma’s vm_private_data (q) to a new vma, causing two munmap triggers t...
