CVE-2024-53063

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> media: dvbdev: prevent the risk of out of memory access<br /> <br /> The dvbdev contains a static variable used to store dvb minors.<br /> <br /> The behavior of it depends if CONFIG_DVB_DYNAMIC_MINORS is set<br /> or not. When not set, dvb_register_device() won&amp;#39;t check for<br /> boundaries, as it will rely that a previous call to<br /> dvb_register_adapter() would already be enforcing it.<br /> <br /> On a similar way, dvb_device_open() uses the assumption<br /> that the register functions already did the needed checks.<br /> <br /> This can be fragile if some device ends using different<br /> calls. This also generate warnings on static check analysers<br /> like Coverity.<br /> <br /> So, add explicit guards to prevent potential risk of OOM issues.
