CVE-2026-23422 Details
Description
In the Linux kernel, the following vulnerability has been resolved: dpaa2-switch: Fix interrupt storm after receiving bad if_id in IRQ handler Commit 31a7a0bbeb00 ("dpaa2-switch: add bounds check for if_id in IRQ handler") introduces a range check for if_id to avoid an out-of-bounds access. If an out-of-bounds if_id is detected, the interrupt status is not cleared. This may result in an interrupt storm. Clear the interrupt status after detecting an out-of-bounds if_id to avoid the problem. Found by an experimental AI code review agent at Google.
A vulnerability in the Linux kernel's dpaa2-switch component can lead to an interrupt storm. This issue arises after the IRQ handler receives a bad if_id, which is not properly cleared, causing repeated interrupt signals. The vulnerability is present in several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel, where this vulnerability has been addressed. Instructions for upgrading can be found in the official Linux kernel documentation.
