Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
crypto: af_alg - Set merge to zero early in af_alg_sendmsg<br />
<br />
If an error causes af_alg_sendmsg to abort, ctx->merge may contain<br />
a garbage value from the previous loop. This may then trigger a<br />
crash on the next entry into af_alg_sendmsg when it attempts to do<br />
a merge that can&#39;t be done.<br />
<br />
Fix this by setting ctx->merge to zero near the start of the loop.
