CVE-2018-18445
CVE-2018-18445 affects the Linux kernel in 4.14.x–4.18.x; prior to 4.18.13, the BPF verifier’s adjust_scalar_min_max_vals mishandles 32-bit right shifts, enabling out-of-bounds memory accesses. Several advisories confirm the issue and reference the fix in 4.18.13 (and backported patches for earli...
