Descriptions

A memory leak flaw was found in the Linux kernel in acrn_dev_ioctl in the drivers/virt/acrn/hsm.c function in how the ACRN Device Model emulates virtual NICs in VM. This flaw allows a local privileged attacker to leak unauthorized kernel information, causing a denial of service.

Se ha encontrado un fallo de pérdida de memoria en el kernel de Linux en la función acrn_dev_ioctl del archivo drivers/virt/acrn/hsm.c en la forma en que el modelo de dispositivo ACRN emula las NIC virtuales en la VM.
