CVE-2026-80610

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: enetc: fix potential divide-by-zero when num_vsi is zero<br /> <br /> For i.MX94 series, all the standalone ENETCs do not support SR-IOV, so<br /> pf-&gt;caps.num_vsi is zero. This leads to a divide-by-zero in<br /> enetc4_default_rings_allocation() when distributing rings among PF and<br /> VFs.<br /> <br /> Division by zero is undefined behavior in C. On ARM64, the UDIV/SDIV<br /> instructions silently return zero rather than raising an exception, so<br /> the issue does not cause a visible crash. However, relying on this<br /> behavior is incorrect and poses a cross-platform compatibility risk.<br /> <br /> Add an explicit check for num_vsi == 0 and return early after the PF&amp;#39;s<br /> rings have been configured.
