CVE-2024-38611: media: i2c: et8ek8: Don't strip remove function when driver is builtin
First published: Wed Jun 19 2024(Updated: )
In the Linux kernel, the following vulnerability has been resolved: media: i2c: et8ek8: Don't strip remove function when driver is builtin Using __exit for the remove function results in the remove callback being discarded with CONFIG_VIDEO_ET8EK8=y. When such a device gets unbound (e.g. using sysfs or hotplug), the driver is just removed without the cleanup being performed. This results in resource leaks. Fix it by compiling in the remove callback unconditionally. This also fixes a W=1 modpost warning: WARNING: modpost: drivers/media/i2c/et8ek8/et8ek8: section mismatch in reference: et8ek8_i2c_driver+0x10 (section: .data) -> et8ek8_remove (section: .exit.text)
