CVE-2021-47608

CVE-2021-47608 involves a bug in the Linux kernel BPF fetch path (bpf: Fix kernel address leakage in atomic fetch) where a faulty check_mem_access() handling could cause leakage of kernel pointers from spilled stack registers when performing atomic XADD. The issue arises in the BPF_FETCH path, wh...
