Описание
In the Linux kernel, the following vulnerability has been resolved:
ASoC: da7219: Fix an error handling path in da7219_register_dai_clks()
If clk_hw_register() fails, the corresponding clk should not be
unregistered.
To handle errors from loops, clean up partial iterations before doing the
goto. So add a clk_hw_unregister().
Then use a while (--i >= 0) loop in the unwind section.
A flaw was found in the Linux kernel's ASoC da7219 audio codec driver. An error handling path in da7219_register_dai_clks() incorrectly attempts to unregister a clock that was never successfully registered. This could lead to incorrect resource cleanup during driver probe failure, potentially causing system instability.
Отчет
This is an error handling path bug that only manifests during driver probe failures for the da7219 audio codec. The issue requires specific hardware (Dialog Semiconductor DA7219) and a failure condition during clock registration. Normal operation is unaffected, and the practical exploit scenario is very limited.
