CVE-2024-27020

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 expr type get() function, which can occur when nft unregister expr() is called concurrently. This may lead to a data-race condition when iterating over the nf tables expressions list. To address this, the function now uses list for each entry rcu() to iterate over the list and rcu read lock() in the caller nft expr type get() to protect the type query process. The vulnerability may impact the confidentiality, integrity, and availability of protected information.

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