CVE-2026-90034

A flaw was found in the Linux kernel's USB MDC800 driver. The driver uses kmalloc instead of kzalloc for buffer allocation, which can leave portions of the allocated memory uninitialized. If a shorter message is received, an attacker could potentially read sensitive information from the kernel...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: usb: image: mdc800: kill download URB on timeout The mdc800deviceread function submits the downloadurb and waits for its completion. If the timeout occurs and the device does not respond, the function returns without terminati...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: usb: image: mdc800: Change kmalloc to kzalloc The kmalloc calls in usbmdc800init, for irqurbbuffer and downloadurbbuffer, have been changed to kzalloc. This prevents potential stack leaks if a shorter message is received in...

CVE-2026-90034

CVE-2026-90034 affects the Linux kernel's usb_mdc800 driver (USB Image MDC800). The root cause is the use of kmalloc() instead of kzalloc() for the irq_urb_buffer and download_urb_buffer allocations in usb_mdc800_init(). Because the memory is not zero-initialized, a shorter-than-expected message ...
