What to do
AI-suggested
A fix for this vulnerability has been implemented in the Linux kernel. Users should update to a Linux kernel version that includes this fix to prevent the concurrency issue and associated memory corruption. Since no specific fixed versions are provided, users should consult the official Linux kernel advisories or source repositories for the patch and apply it accordingly.
Description
A concurrency issue in the Linux kernel's mvpp2 network driver could cause parser TCAM memory corruption. This occurs due to unprotected concurrent modifications of TCAM/SRAM tables and their cached shadow SRAM, leading to potential data corruption and packet drops. The flaw was observed when mvpp2_set_rx_mode() executed simultaneously on two CPUs, corrupting an entry and causing the classifier to drop all incoming unicast packets.
