Short explanation
CVE-2026-98630 is a flaw in the Linux kernel fbnic driver where an error pointer is passed to page_pool_destroy() during payload page pool cleanup. This can dereference the error pointer and leave the header page pool allocated, causing a memory leak.
Memory leaks can exhaust system resources, leading to service disruption and instability.
What should be done?
- Monitor official kernel releases for updates
- Apply patches promptly when available
- Since patch status is unknown, follow vendor advisory
- Consider mitigation measures for affected versions
