Описание

In do_ipt_get_ctl and do_ipt_set_ctl of ip_tables.c, there is a possible way to leak kernel information due to uninitialized data. This could lead to local information disclosure with system execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-120612905References: Upstream kernel

A vulnerability was found in the Linux kernel’s net/ipv6/netfilter/ip6_tables.c:copy_entries_to_user function. This flaw allows a local attacker to leak internal kernel information.

Меры по смягчению последствий

To mitigate this issue, prevent the module ip6_tables from being loaded. Please see https://access.redhat.com/solutions/41278 for information on how to blacklist a kernel module to prevent it from loading automatically.
