kernel: memory leak in af9005_identify_state() function in drivers/media/usb/dvb-usb/af9005.c
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.
Mitigation: 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
