Описание
In the Linux kernel, the following vulnerability has been resolved:
ASoC: Intel: bytcr_rt5640: Fix invalid quirk input mapping
When an invalid value is passed via quirk option, currently
bytcr_rt5640 driver only shows an error message but leaves as is.
This may lead to unepxected results like OOB access.
This patch corrects the input mapping to the certain default value if
an invalid value is passed.
A flaw was found in the Linux kernel’s ASoC Intel bytcr_rt5640 driver. When an invalid value is passed via the driver’s “quirk” input option, the driver merely logs an error and retains the invalid value, rather than correcting it. This can result in out-of-bounds (OOB) memory access.
Меры по смягчению последствий
To mitigate this issue, prevent module snd-soc-core from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
