Attack-Flow Graph
AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability in the Linux kernel's netfilter ipset component is due to a missing macro called IP_SET_HASH_WITH_NET0 in the ip_set_hash_netportnet.c file. The absence of this macro causes incorrect calculation of array offsets using CIDR_POS(c), which can result in an integer underflow. This underflow can lead to slab out-of-bound memory access, potentially causing instability or security issues. The vulnerability is fixed by adding back the missing macro.
How can this vulnerability impact me? :
The vulnerability can lead to slab out-of-bound memory access in the Linux kernel, which may cause system instability, crashes, or potentially allow an attacker to exploit the kernel memory corruption for privilege escalation or denial of service.
