*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
dm-verity-fec: fix reading parity bytes split across blocks (take 3)<br />
<br />
fec_decode_bufs() assumes that the parity bytes of the first RS codeword<br />
it decodes are never split across parity blocks.<br />
<br />
This assumption is false. Consider v->fec->block_size == 4096 &&<br />
v->fec->roots == 17 && fio->nbufs == 1, for example. In that case, each<br />
call to fec_decode_bufs() consumes v->fec->roots * (fio->nbufs
