The vulnerability of the lan966x_fdma_reload() function in the drivers/net/ethernet/microchip/lan966x/lan966x_fdma.c file of the Ethernet microchip Linux kernel driver allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the lan966xfdmareload function in the drivers/net/ethernet/microchip/lan966x/lan966xfdma.c file of the Ethernet microchip Linux kernel driver is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the...
