NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debuginfo-common-aarch64 package and not the kernel-debuginfo-common-aarch64 package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

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().
