What the advisory describes
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.
Source: EUVD (ENISA), in the words of the advisory.
