Meltdown. A local attacker could use this to expose sensitive information,

Packet Filter (BPF) implementation in the Linux kernel did not properly check
the relationship between pointer values and the BPF stack. A local attacker
could use this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2017-17863) Jann Horn discovered that the Berkeley Packet
Filter (BPF) implementation in the Linux kernel improperly performed sign
extension in some situations. A local attacker could use this to cause a denial
of service (system crash) or possibly execute arbitrary code. (CVE-2017-16995)
Alexei Starovoitov discovered that the Berkeley Packet Filter (BPF)
implementation in the Linux kernel contained a branch-pruning logic issue around
unreachable code. A local attacker could use this to cause a denial of service.
