CVE-2022-48922

A vulnerability was found in the Linux Kernel's RISC-V architecture, caused by improper handling of the frame pointer ($fp) in the trace_hardirqs_{on,off}() functions. These functions rely on the CALLER_ADDR1 macro to retrieve caller information, but if $fp is repurposed for other uses, it can lead to memory access faults, resulting in kernel NULL pointer dereferences during boot.
