Summary
CVE-2026-23180 affecting package kernel for versions less than 6.6.126.1-1
Details

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 ifid from the upper 16 bits of the hardware status register and uses it to index into ethsw->ports[] without validation. Since ifid can be any 16-bit value (0-65535) but the ports array is only allocated with swattr.numifs 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 dpaa2switchrx().
