CVE-2018-18445 is a high-severity vulnerability affecting specific versions of the Linux kernel (4.14.x through 4.18.x before 4.18.13), including those used by Canonical and Red Hat. It stems from faulty numeric bounds computation in the BPF verifier, specifically mishandling 32-bit right shifts, which can lead to out-of-bounds memory accesses. This local attack requires low privileges and complexity, but could result in high impact to confidentiality, integrity, and availability. There is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
