Description OSIDB Bzimport 2025-10-01 12:06:16 UTC

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.
