CWE
- CWE-416 - Use After Free
Summary
A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c.
Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local attacker with user access to cause a privilege escalation issue.
We recommend upgrading past commit 1240eb93f0616b21c675416516ff3d74798fdc97.

CWE
- CWE-787 - Out-of-bounds Write
Summary
A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to achieve local privilege escalation.
The out-of-bounds write is caused by missing skb->cb initialization in the ipvlan network driver. The vulnerability is reachable if CONFIG_IPVLAN is enabled.
We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e.
