CVE-2023-54322
arm64: set __exception_irq_entry with __irq_entry as a default
Description
In the Linux kernel, the following vulnerability has been resolved: arm64: set __exception_irq_entry with __irq_entry as a default filter_irq_stacks() is supposed to cut entries which are related irq entries from its call stack. And in_irqentry_text() which is called by filter_irq_stacks() uses __irqentry_text_start/end symbol to find irq entries in callstack. But it doesn't work correctly as without "CONFIG_FUNCTION_GRAPH_TRACER", arm64 kernel doesn't include gic_handle_irq which is entry point of arm64 irq between __irqentry_text_start and __irqentry_text_end as we discussed in below link. https://lore.kernel.org/all/CACT4Y+aReMGLYua2rCLHgFpS9io5cZC04Q8GLs-uNmrn1ezxYQ@mail.gmail.com/#t This problem can makes unintentional deep call stack entries especially in KASAN enabled situation as below.
