CVE-2026-68369

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: printer: fix infinite loop in printerread printerread uses the same variable for the requested copy size and the number of bytes actually copied to user space. copytouser returns the number of bytes not copied, so wh...

CVE-2026-68369

The CVE affects the Linux kernel USB gadget printer driver (printer_read) where the code used the same variable for the requested copy size and the actual copied bytes. If copy_to_user fails to copy anything, the copied length becomes zero and RX data can cause an infinite loop because len/buf/cu...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fixed a double-free in rxesrqfrominit. In rxesrqfrominit, the queue pointer ‘q’ is assigned to ‘srq-rq.queue’ before copying the SRQ number to user space. If copytouser fails, the function calls rxequeuecleanup to free...

CVE-2026-64290

A flaw was found in the Linux kernel's iommufd component. When a copytouser operation fails within the iommufdfaultfopsread function, the system enters an infinite loop. This continuous retry consumes 100% of the CPU and holds a mutex, which can lead to a denial of service DoS for affected system...
