CVE-2026-46130

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-&gt;fec-&gt;block_size == 4096 &amp;&amp;<br /> v-&gt;fec-&gt;roots == 17 &amp;&amp; fio-&gt;nbufs == 1, for example. In that case, each<br /> call to fec_decode_bufs() consumes v-&gt;fec-&gt;roots * (fio-&gt;nbufs
