Описание
A memory leak in the af9005_identify_state() function in drivers/media/usb/dvb-usb/af9005.c in the Linux kernel through 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-2289adbfa559.
A flaw was found in the Afatech 9005 DVB-T receiver driver in the Linux kernel. An attacker, with physical access to the system, could cause the system to crash following a resource cleanup. The highest threat from this vulnerability is to system availability.
Меры по смягчению последствий
In order to mitigate this issue it is possible to prevent the affected code from being loaded by blacklisting the kernel module dvb-usb-af9005. For instructions relating to how to blacklist a kernel module refer to: https://access.redhat.com/solutions/41278
