BPF JIT compilers in the Linux kernel through 5.11.12 have incorrect computation of branch displacements, allowing them to execute arbitrary code within the kernel context. This affects arch/x86/net/bpf_jit_comp.c and arch/x86/net/bpf_jit_comp32.c. CREATE(Triage):(User=admin) [CVE-2021-29154|https://nvd.nist.gov/vuln/detail/CVE-2021-29154]
