CVE-2024-38611

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: medios: i2c: et8ek8: No eliminar la función de eliminación cuando el controlador está integrado. El uso de __exit para la función de eliminación hace que la devolución de llamada de eliminación se descarte con CONFIG_VIDEO_ET8EK8=y. Cuando un dispositivo de este tipo se desvincula (por ejemplo, usando sysfs o hotplug), el controlador simplemente se elimina sin que se realice la limpieza. Esto da como resultado fugas de recursos. Solucionarlo compilando la devolución de llamada de eliminación incondicionalmente. Esto también corrige una advertencia de modpost W=1: ADVERTENCIA: modpost: drivers/media/i2c/et8ek8/et8ek8: sección no coincide en referencia: et8ek8_i2c_driver+0x10 (sección: .data) -> et8ek8_remove (sección: .exit.text)

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)

It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate certain SMB messages, leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service or possibly expose sensitive information. Supraja Sridhara, Benedict Schlüter, Mark Kuhne, Andrin Bertschi, and Shweta Shinde discovered that the Confidential Computing framework in the Linux kernel for x86 platforms did not properly handle 32-bit emulation on TDX and SEV. An attacker with access to the VMM could use this to cause a denial of service or possibly execute arbitrary code.
