CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's handling of fib_rules during the dumping process, specifically when a dying fib_rule is encountered, which can lead to improper reference counting and potential instability. This issue could impact systems relying on network routing functionalities that utilize fib_rules, making it critical for organizations managing Linux-based environments to prioritize updates. Network administrators and security teams should address this vulnerability to ensure the stability and security of their systems.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: net: fib_rules: Don't dump dying fib_rule in fib_rules_dump(). rocker_router_fib_event() calls fib_rule_get() during RCU dump. If the fib_rule is dying, refcount_inc() will complain about it. Let's call refcount_inc_not_zero() in fib_rules_dump().
