CVE-2026-23378
Description
A flaw was found in the Linux kernel, specifically within the networking scheduler's Ingress Forwarding Engine (IFE) action. When an IFE action attempts to replace metadata, it incorrectly appends new metadata instead of replacing the old. This unbounded addition of metadata can lead to an out-of-bounds memory write during the encoding operation. An attacker, by manipulating network traffic, could potentially trigger a denial of service or achieve arbitrary code execution within the kernel.
Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of the product's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the product into an infinite loop.
