In the Linux kernel, the following vulnerability has been resolved:

parisc: Increase kernel stack size to 32kb

For 64-bit Linux kernels, increase the default kernel stack size (THREAD_SIZE_ORDER) to 32 kB, in order to avoid kernel crashes which have been triggered recently when building the debian vtk9 package with gcc 17:
