| Null-dereference in panic()
| Null-dereference in panic()
| The Switch's stage 1 bootloader, on panic(), clears the stack and then attempts to clear the Security Engine. However, it does so by dereferencing a pointer to the SE in .bss (initially NULL), and this pointer doesn't get initialized until partway into the bootloader's main() after several functions that might panic() are called. Thus, a panic() caused prior to SE initialization would result in the SE pointer still being NULL when dereferenced.

The BPMP doesn't have an active MPU and the bus won't data abort on an invalid address, so no exception will be entered: it'll end up overwriting some exception vectors with NULL before halting.

It then validates package1 before jumping to it by checking the PK11 magic number, and that the section sizes sum to the expected size (and are individually less than the expected size).
However, package1ldr does not actually validate the package1 key against a fixed vector (much like kernel9loader forgot to do so on the 3ds). This would normally not matter, as keyblobs are validated -- however, with bootrom code execution one can dump SBK and forge keyblobs, and thus control the package1 key.

| When an [[SMC]] is called, TrustZone sets a global variable to mark that an SMC is in progress, so that two SMCs using shared resources (like the security engine) do not trample on one another. On 1.0.0, this global variable was written using non-atomic writes, and thus a race condition is possible.

However, the SMC handler enforces that all SMCs must be called from core #3, unless the top-level handler ID is 1 (SMCs internal to the kernel). Thus, the only SMCs that can be run side-by-side are [any userland smc] and smcGetRandomBytesForKernel, and this turns out to not really be abusable.

| Missed BPMP Exception Vector Writes
| Missed BPMP Exception Vector Writes
| Starting in [[2.0.0]], the BPMP is asleep at runtime, and is turned on by TrustZone during [[SMC|smcCpuSuspend]] in order to initiate the deep sleep process. When it does so, it is held in RESET, and TrustZone attempts to write to the BPMP exception vectors at 0x6000F200 to register EVP_RESET = lp0_entry_fw_crt0, and all other EVPs to a function that simply reboots. However, while they successfully write EVP_RESET, they miss all the other vectors, accidentally writing to the 0x6000F004-0x6000F020 region instead of the 0x6000F204-0x6000F220 region they want to write to. This results in all the exception vectors for the BPMP other than RESET being "undefined" (attacker controlled).

With some way of causing an exception vector to be taken at the right time, this would give pre-sleep code execution (and thus arbitrary TrustZone code execution, via the security engine flaw). However, none of the abort vectors are really triggerable, and interrupts are disabled for the BPMP when it is taken out of reset. Thus, this is useless in practice.

| CVE-2016-4657
| WebKit vuln discovered around August 2016. Most notably used in the iOS 9.3.X exploit. A simple PoC can be found [https://github.com/LiveOverflow/lo_nintendoswitch/blob/master/poc1.html here]. This was later exploited by [https://twitter.com/qwertyoruiopz Qwertyoruiop] using an adjusted version of his iOS 9.3 webkit exploit (others exploited this prior to then).

| [[HID_services|hidbus]] GetJoyPollingReceivedData buffer overflow
| hidbus GetJoyPollingReceivedData doesn't validate the u8 size used for memcpy, when copying the data to the output JoyPollingReceivedData. With 11.x, the size is now clamped to a maximum of 0x2C (regardless of polling-mode). Note that 0x2C is the data-size for JoyButtonOnlyPollingDataAccessor, the other polling-modes have a smaller size.
The hid-sysmodule code which writes data here does handle it properly: size is clamped to a max size, and the data-read uses a fixed-size anyway (hence there's no way to trigger this sdknso vuln with the hid-sysmodule tmem writing code).
This could only be exploited if one directly writes to the tmem when one has previously compromised hid-sysmodule, without using the normal tmem-writing func for this.
There are only a few [[HID_services#ExternalDevices|apps]] which use hidbus.
