Vulnerability description
DayBreach CVE AI Research
CVE-2023-42753 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash the system or potentially escalate their privileges on the system.
