CVE-2020-8835: Out-of-bounds Read

In the Linux kernel 5.5.0 and newer, the bpf verifier kernel/bpf/verifier.c did not properly restrict the register bounds for 32-bit operations, leading to out-of-bounds reads and writes in kernel memory. The vulnerability also affects the Linux 5.4 stable series, starting with v5.4.7, as the...

CVE-2018-18445

A security flaw was found in the Linux kernel in the adjustscalarminmaxvals function in kernel/bpf/verifier.c. A faulty computation of numeric bounds in the BPF verifier permits out-of-bounds memory accesses because this function mishandles 32-bit right shifts. A local unprivileged user cannot...
