CVE-2024-39484

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mmc: davinci: 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_MMC_DAVINCI=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/mmc/host/davinci_mmc: falta de coincidencia de sección en referencia: davinci_mmcsd_driver+0x10 (sección: .data) -> davinci_mmcsd_remove (sección: .exit.text)

In the Linux kernel, the following vulnerability has been resolved: mmc: davinci: Don't strip remove function when driver is builtin Using __exit for the remove function results in the remove callback being discarded with CONFIG_MMC_DAVINCI=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/mmc/host/davinci_mmc: section mismatch in reference: davinci_mmcsd_driver+0x10 (section: .data) -> davinci_mmcsd_remove (section: .exit.text)

Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition, leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a denial of service.
