CVE-2017-16995

Priority
High
Description
The check_alu_op function in kernel/bpf/verifier.c in the Linux kernel
through 4.14.8 allows local users to cause a denial of service (memory
corruption) or possibly have unspecified other impact by leveraging
incorrect sign extension.
Ubuntu-Description
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.
