In the Linux kernel, the following vulnerability has been resolved:
riscv, bpf: Fix kernel stack corruption in tailcall with CFI
When CONFIG_CFI_CLANG is enabled, prog->bpf_func already skips the kcfi
instruction during setup. Including it again in the tailcall jump offset
causes it to jump over an extra 4 bytes, skipping the stack pointer
adjustment, which will result in kernel stack corruption.
