Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
wl1251: dynamically allocate memory used for DMA<br />
<br />
With introduction of vmap&#39;ed stacks, stack parameters can no<br />
longer be used for DMA and now leads to kernel panic.<br />
<br />
It happens at several places for the wl1251 (e.g. when<br />
accessed through SDIO) making it unuseable on e.g. the<br />
OpenPandora.<br />
<br />
We solve this by allocating temporary buffers or use wl1251_read32().<br />
<br />
Tested on v5.18-rc5 with OpenPandora.
