CVE-2020-27170
The CVE-2020-27170 flaw affects the Linux kernel prior to 5.11.8, where in kernel/bpf/verifier.c there is undesirable out-of-bounds speculation on pointer arithmetic. This can enable a side-channel attack that defeats Spectre mitigations and may allow an attacker to obtain sensitive information f...
CVE-2020-27170
A flaw was found in the Linux kernels eBPF verification code. By default accessing the eBPF verifier is only accessible to privileged users with CAPSYSADMIN. A local user with the ability to insert eBPF instructions can use the eBPF verifier to abuse a spectre like flaw where they can infer all...
