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. (NVD)
