Описание
A flaw was found in the Linux kernel's imx8-isi media driver. This use-after-free vulnerability occurs during the removal of the driver due to an incorrect order of cleanup operations. A local attacker could potentially exploit this to cause a denial of service or achieve arbitrary code execution.
