Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> hwmon: (powerz) Avoid cacheline sharing for DMA buffer<br /> <br /> Depending on the architecture the transfer buffer may share a cacheline<br /> with the following mutex. As the buffer may be used for DMA, that is<br /> problematic.<br /> <br /> Use the high-level DMA helpers to make sure that cacheline sharing can<br /> not happen.<br /> <br /> Also drop the comment, as the helpers are documentation enough.<br /> <br /> https://sashiko.dev/#/message/20260408175814.934BFC19421%40smtp.kernel.org
