Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
ovpn: fix NULL dereference when killing missing key<br />
<br />
ovpn_crypto_kill_key assumes both crypto slots are populated and<br />
dereferences each slot before checking it. That is not guaranteed: a<br />
peer can have only one installed key, and the kill path may be asked to<br />
remove a key that is not present.<br />
<br />
Read each slot once while holding the crypto state lock, check for NULL<br />
before looking at key_id, and only replace the slot that actually<br />
matches.
