A flaw was found in the Linux kernel's verisilicon hantro_vpu media driver. When the driver is built as a module, a misuse of the __initconst annotation causes data to be prematurely freed. This freed memory is later accessed during driver probing or unbind-bind cycles, leading to a kernel panic and a Denial of Service (DoS) condition. A local attacker could potentially trigger this flaw by loading and unloading the affected module.
