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

Noroxi assessment

Priority: Monitor (action score 28/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.14% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: Linux Linux 1b381a638e1851d8cfdfe08ed9cdbec5295b18c9, 2447edc367800ba914acf7ddd5d250416b45fb31, 31a7a0bbeb006bac2d9c81a2874825025214b6d8.

Low priority for now. Upgrade to Linux Linux 1b381a638e1851d8cfdfe08ed9cdbec5295b18c9, 2447edc367800ba914acf7ddd5d250416b45fb31, 31a7a0bbeb006bac2d9c81a2874825025214b6d8 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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().
