In the Linux kernel, the following vulnerability has been resolved:

bpf: Reject writes through untrusted BTF pointers

check_ptr_to_btf_access() lets program-type btf_struct_access callbacks

validate writes before the default BTF access path rejects non-read

accesses. That bypasses the read-only policy for untrusted BTF pointers

created by helpers such as bpf_rdonly_cast().

Reject non-read accesses through PTR_UNTRUSTED BTF pointers at the

common entry point, before the callback branch to handle all cases. (NVD)
