Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
crypto: algif_aead - Revert to operating out-of-place<br />
<br />
This mostly reverts commit 72548b093ee3 except for the copying of<br />
the associated data.<br />
<br />
There is no benefit in operating in-place in algif_aead since the<br />
source and destination come from different mappings. Get rid of<br />
all the complexity added for in-place operation and just copy the<br />
AD directly.
