Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
xsk: validate launch-time metadata size<br />
<br />
Launch-time metadata extends beyond the first 16 bytes of struct<br />
xsk_tx_metadata. Reject the request when the registered metadata area does<br />
not contain the complete field.<br />
<br />
Snapshot the validated flags for the generic transmit path and use that<br />
snapshot for request and completion processing, avoiding inconsistent<br />
decisions if user space changes the flags concurrently.<br />
<br />
Note that only xsk_skb_metadata is properly using the flags,<br />
__xsk_buff_get_metadata ignores them. Next commits address that.
