Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: hwmon: nzxt-smart2 DMA-aligned output buffer Sashiko reports that when sendoutputreport calls hidhwoutputreport, the underlying USB HID core calls usbinterruptmsg, which directly maps this buffer for DMA operations. When the DMA...

CVE-2026-74551

CVE-2026-74551 affects the Linux kernel hwmon path for nzxt-smart2. The issue arises when send_output_report() triggers USB HID DMA mapping via hid_hw_output_report(), which maps the output buffer for DMA using usb_interrupt_msg(). On non-coherent CPUs (e.g., ARM/MIPS), flushing/invalidating the ...
