High impact if exploited, but EPSS currently rates exploitation as unlikely (0.20%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In the Linux kernel, the following vulnerability has been resolved: platform/chrome: cros_ec_chardev: fix kernel data leak from ioctl It is possible to peep kernel page's data by providing larger `insize` in struct cros_ec_command[1] when invoking EC host commands. Fix it by using zeroed memory. [1]: https://elixir.bootlin.com/linux/v6.2/source/include/linux/platform_data/cros_ec_proto.h#L74
