CVE-2026-23056

In the Linux kernel, the following vulnerability has been resolved: uacce: implement mremap in uaccevmops to return -EPERM The current uaccevmops does not support the mremap operation of vmoperationsstruct. Implement .mremap to return -EPERM to remind users. The reason we need to explicitly disab...

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...
