Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
pktgen: Avoid out-of-bounds access in get_imix_entries<br />
<br />
Passing a sufficient amount of imix entries leads to invalid access to the<br />
pkt_dev->imix_entries array because of the incorrect boundary check.<br />
<br />
UBSAN: array-index-out-of-bounds in net/core/pktgen.c:874:24<br />
index 20 is out of range for type &#39;imix_pkt [20]&#39;<br />
CPU: 2 PID: 1210 Comm: bash Not tainted 6.10.0-rc1 #121<br />
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996)<br />
