Description

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