NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-rt-devel package and not the kernel-rt-devel package as distributed by Centos.
In the Linux kernel, the following vulnerability has been resolved:
net: fix potential refcount leak in ndisc_router_discovery()
The issue happens on specific paths in the function. After both the
object rt and neigh are grabbed successfully, when lifetime is
nonzero but the metric needs change, the function just deletes the
route and set rt to NULL. Then, it may try grabbing rt and neigh
again if above conditions hold. The function simply overwrite neigh
if succeeds or returns if fails, without decreasing the reference
count of previous neigh. This may result in memory leaks.
Fix it by decrementing the reference count of neigh in place.
