CVE-2024-27019

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

Description The issue is related to a potential data-race in the nft obj type get() function in the nf tables component of the Linux kernel. This occurs because nft unregister obj() can run concurrently with nft obj type get(), and there is no protection when iterating over the nf tables objects list in nft obj type get(). This can lead to a potential data-race of the nf tables objects list entry. To resolve this, list for each entry rcu() is used to iterate over the nf tables objects list in nft obj type get(), and rcu read lock() is used in the caller nft obj type get() to protect the entire type query process.

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