This array is passed to usb_check_int_endpoints function from usb.c core driver, which executes a for loop that iterates over the elements of the passed array. Not finding a null element at the end of the array, it tries to read the next, non-existent element, crashing the kernel. To fix this, a 0 element was added at the end of the array to break the for loop.

Affected files ============== The file(s) affected by this issue are: drivers/hid/hid-thrustmaster.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/436f48c864186e9413d1b7c6e91767cc9e1a65b8 https://git.kernel.org/stable/c/f3ce05283f6cb6e19c220f5382def43dc5bd56b9 https://git.kernel.org/stable/c/cdd9a1ea23ff1a272547217100663e8de4eada40 https://git.kernel.org/stable/c/73e36a699b9f46322ffb81f072a24e64f728dba7 https://git.kernel.org/stable/c/0b43d98ff29be3144e86294486b1373b5df74c0e
