Description

In bpf_skb_change_head of filter.c, there is a possible out of bounds read due to a use after free. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-154177719References: Upstream kernel An out-of-bounds (OOB) memory access flaw was found in net/core/filter.c in __bpf_skb_max_len in the Linux kernel. A missing sanity check to the current MTU check may allow a local attacker with special user privilege to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information.
