  "description": "In the Linux kernel, the following vulnerability has been resolved:  net: arc_emac: Fix use after free in arc_mdio_probe()  If bus-\u003Estate is equal to MDIOBUS_ALLOCATED, mdiobus_free(bus) will free the \u0022bus\u0022. But bus-\u003Ename is still used in the next line, which will lead to a use after free.  We can fix it by putting the name in a local variable and make the bus-\u003Ename point to the rodata section \u0022name\u0022,then use the name in the error message without referring to bus to avoid the uaf.",
