A vulnerability in the Linux kernel's BPF subsystem on arm64 architecture was resolved by properly setting the frame pointer for the exception callback. The flaw caused the callback prologue to omit setting the frame pointer register, leading to potential use of stale stack frame pointers from subprograms that never return. This could allow a helper function to overwrite its own return address, potentially causing a kernel panic or fatal exception. The fix ensures the frame pointer register is correctly set on the exception callback path, preventing this unsafe condition.
