A fix is available — apply it.

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

arm64: Don't call NULL in do_compat_alignment_fixup()

do_alignment_t32_to_handler() only fixes up alignment faults for specific instructions; it returns NULL otherwise (e.g. LDREX). When that's the case, signal to the caller that it needs to proceed with the regular alignment fault handling (i.e. SIGBUS). Without this patch, the kernel panics:
