Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A vulnerability in the Linux kernel has been resolved. The issue is related to the ndisc send skb() function, which can be called without RTNL or RCU held, potentially leading to a use-after-free (UAF) condition. To address this, RCU protection has been extended in ndisc send skb() by acquiring rcu read lock() earlier, allowing the use of dev net rcu().
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
