CVE-2026-23180

The CVE-2026-23180 issue affects the Linux kernel's dpaa2-switch code, where an IRQ handler could read beyond the ports[] array due to an unvalidated 16-bit if_id. The root cause is a missing bounds check before indexing ethsw->ports[], leading to an out-of-bounds read. The description in the ...

CVE-2026-23180 dpaa2-switch: add bounds check for if_id in IRQ handler

In the Linux kernel, the following vulnerability has been resolved: dpaa2-switch: add bounds check for ifid 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...
