CVE-2026-74288

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the fib rules component where the fib rules dump() function may attempt to dump a dying fib rule. This occurs because rocker router fib event() calls fib rule get() during an RCU (Read-Copy-Update) dump. If the fib rule is in a dying state, the refcount inc() function will trigger a complaint or error. The fix involves using refcount inc not zero() within fib rules dump() to prevent this behavior.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
