Linux · Linux Kernel · CVE-2023-0179
**Name of the Vulnerable Software and Affected Versions**
Linux kernel versions 5.5 through 6.2-rc3
**Description**
A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel, specifically in nftables. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution. The vulnerability is related to a stack buffer-overflow in the netfilter subsystem from the softirq context.
**Recommendations**
For Linux kernel versions 5.5 through 6.2-rc3, consider disabling the nftables subsystem as a temporary workaround until a patch is available. Restrict access to the vulnerable Netfilter subsystem to minimize the risk of exploitation. Avoid using the nftables functionality in the affected Linux kernel versions until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
