CVE-2026-23180

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> dpaa2-switch: add bounds check for if_id in IRQ handler<br /> <br /> The IRQ handler extracts if_id from the upper 16 bits of the hardware<br /> status register and uses it to index into ethsw-&gt;ports[] without<br /> validation. Since if_id can be any 16-bit value (0-65535) but the ports<br /> array is only allocated with sw_attr.num_ifs elements, this can lead to<br /> an out-of-bounds read potentially.<br /> <br /> Add a bounds check before accessing the array, consistent with the<br /> existing validation in dpaa2_switch_rx().
