In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
serial: core: do fallible allocations before the console can be registered<\/p>\n
serial_core_add_one_port() allocates uport->tty_groups after
\nuart_configure_port(), which may register the console. If the allocation
\nfails, the driver unwinds the port while its console remains registered.
\nThe earlier uport->name allocation has a related failure path that leaves
\nstate->uart_port linked to a port being freed.<\/p>\n
Failslab reproduced a NULL dereference in PL011 console output and a KASAN
\nuse-after-free in i.MX console output after failed binds.<\/p>\n
Allocate the name and tty_groups before linking the port and configuring
\nit. Reserve space for the optional driver attribute group because
\nconfig_port() may populate uport->attr_group during configuration.<\/p>\n","protected":false},"excerpt":{"rendered":"
