Description SMASH SMASH 2024-02-26 13:34:17 UTC 
In the Linux kernel, the following vulnerability has been resolved:

serial: imx: fix tx statemachine deadlock

When using the serial port as RS485 port, the tx statemachine is used to
control the RTS pin to drive the RS485 transceiver TX_EN pin. When the
TTY port is closed in the middle of a transmission (for instance during
userland application crash), imx_uart_shutdown disables the interface
and disables the Transmission Complete interrupt. afer that,
imx_uart_stop_tx bails on an incomplete transmission, to be retriggered
by the TC interrupt. This interrupt is disabled and therefore the tx
statemachine never transitions out of SEND. The statemachine is in
deadlock now, and the TX_EN remains low, making the interface useless.

imx_uart_stop_tx now checks for incomplete transmission AND whether TC
interrupts are enabled before bailing to be retriggered. This makes sure
the state machine handling is reached, and is properly set to
WAIT_AFTER_SEND.

Comment 1 Thomas Leroy 2024-02-26 13:34:51 UTC 
stable and SLE15-SP6 already fixed. cve/linux-5.14 only is missing the patch.
Comment 3 Jiri Slaby 2024-03-04 11:18:27 UTC 
FTR
commit 78d60dae9a0c9f09aa3d6477c94047df2fe6f7b0
Author: Paul Geurts <paul_geurts@live.nl>
Date:   Fri Nov 24 14:11:10 2023 +0100

    serial: imx: fix tx statemachine deadlock

is in v6.8-rc1
Comment 4 Jiri Slaby 2024-03-04 11:25:50 UTC 
FTR
Fixes: cb1a60923609 ("serial: imx: implement rts delaying for rs485")
from v5.9-rc1

So as in:
(In reply to Thomas Leroy from comment #1)
> stable and SLE15-SP6 already fixed.

Updated references here.

> cve/linux-5.14 only is missing the patch.

And committed here.
Comment 5 Jiri Slaby 2024-03-04 11:26:20 UTC
