NOTE: this issue might only affect kernel versions before 2.6.16.x.

The host_start function in drivers/usb/chipidea/host.c in the Linux kernel before 3.7.4 does not properly support a certain non-streaming option, which allows local users to cause a denial of service (system crash) by sending a large amount of network traffic through a USB/Ethernet adapter.

An issue was discovered in the Linux kernel 4.18 through 5.6.11 when unprivileged user namespaces are allowed. A user can create their own PID namespace, and mount a FUSE filesystem. Upon interaction with this FUSE filesystem, if the userspace component is terminated via a kill of the PID namespace's pid 1, it will result in a hung task, and resources being permanently locked up until system reboot. This can result in resource exhaustion.

NOTE: This has been disputed as not a vulnerability because "rhashtable_init() can only fail if it is passed invalid values in the second parameter's struct, but when invoked from sdma_init() that is a pointer to a static const struct, so an attacker could only trigger failure if they could corrupt kernel memory (in which case a small memory leak is not a significant problem).
