[CVE-2022-34918] A crack in the Linux firewall
[CVE-2022-34918] A crack in the Linux firewall
In our previous article Yet another bug into Netfilter, I presented a vulnerability found within the netfilter subsystem of the Linux kernel. During my investigation, I found a weird comparison that does not fully protect a copy within a buffer. It led to a heap buffer overflow that was exploited to obtain root privileges on Ubuntu 22.04.
