CVE-2023-53495 Details
Description
In the Linux kernel, the following vulnerability has been resolved: net: ethernet: mvpp2_main: fix possible OOB write in mvpp2_ethtool_get_rxnfc() rules is allocated in ethtool_get_rxnfc and the size is determined by rule_cnt from user space. So rule_cnt needs to be check before using rules to avoid OOB writing or NULL pointer dereference.
A vulnerability allowing a potential out-of-bounds write has been identified in the Linux kernel's MVPP2 Ethernet driver. This issue arises in the 'mvpp2_ethtool_get_rxnfc' function, where the size of the 'rules' array is determined by 'rule_cnt' from user space. If 'rule_cnt' is not properly validated before use, it can lead to out-of-bounds writes or null pointer dereferences.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been patched. The specific commit addressing this issue is '349638f7e5d3c7d328565587bb7b0454bbee02e2', which is included in the Linux kernel stable tree.
