Descriptions
kernel/bpf/verifier.c in the Linux kernel before 4.20.6 performs undesirable out-of-bounds speculation on pointer arithmetic in various cases, including cases of different branches with different state or limits to sanitize, leading to side-channel attacks.
En el kernel de Linux, en versiones anteriores a la 4.20.6, "kernel/bpf/verifier.c" realiza especulaciones fuera de límites no deseables en la aritmética de punteros en varias ocasiones, incluyendo casos de diferentes ramas con distintos estados o límites que hay que sanear, conduciendo a ataques de canal lateral.
It has been discovered that the Linux eBPF Spectre v1 mitigation is insufficient.
