CVE-2026-98883
Beschrijving NL
In the Linux kernel, the following vulnerability has been resolved:
serial: 8250_port: recognize UPIO_AU
My MIPS Alchemy systems generate the following warning during
probe of the 8250 driver:
WARNING: drivers/tty/serial/8250/8250_port.c:462 at set_io_from_upio+0xfc/0x124, CPU#0: swapper/0/1
Unsupported UART type 4
[...]
[] set_io_from_upio+0xfc/0x124
[] serial8250_set_defaults+0x94/0xe0
[] serial8250_register_8250_port+0x288/0x51c
[] serial8250_probe+0x160/0x1e8
[] platfo rm_probe+0x64/0x90
The least invasive fix is to recognize UPIO_AU (type 4) in set_io_from_upio()
and do nothing, since all parameters have already been set up in
8250_rt288x.c::au_platform_setup(). Run-tested on Alchemy Au1300 platform.
