libseccomp-golang 0.9.0 and earlier incorrectly generates BPFs that OR multiple arguments rather than ANDing them. A process running under a restrictive seccomp filter that specified multiple syscall arguments could bypass intended access restrictions by specifying a single matching argument.

Exploit prediction (EPSS)

2.43% probability of exploitation in the next 30 days, higher than 84% of all scored CVEs.
