CVE-2023-2163

Incorrect verifier pruning in BPF in Linux Kernel >=5.4 leads to unsafe code paths being incorrectly marked as safe, resulting in arbitrary read/write in kernel memory, lateral privilege escalation, and container escape.

Incorrect verifier pruning in BPF in Linux Kernel >=5.4 leads to unsafe code paths being incorrectly marked as safe, resulting in arbitrary read/write in kernel memory, lateral privilege escalation, and container escape.

La poda incorrecta del verificador en BPF en el kernel de Linux >=5.4 conduce a que las rutas de código inseguras se marquen incorrectamente como seguras, lo que resulta en lectura/escritura arbitraria en la memoria del kernel, escalada de privilegios lateral y escape de contenedor.
