CVE-2026-23422

CVE-2026-23422 concerns the Linux kernel’s dpaa2-switch component. An out-of-bounds if_id detected in the IRQ handler could leave the interrupt status uncleared, potentially causing an interrupt storm and a DoS-like condition. The technical details in connected documents show the root cause as mi...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the dpaa2-switch interrupt handler not clearing the interrupt state after detecting an out-of-bounds...

CVE-2026-23206

In the Linux kernel, the following vulnerability has been resolved: dpaa2-switch: prevent ZEROSIZEPTR dereference when numifs is zero The driver allocates arrays for ports, FDBs, and filter blocks using kcalloc with ethsw-swattr.numifs as the element count. When the device reports zero interfaces...

SUSE CVE-2026-23180

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...

CVE-2026-23206

Summary: CVE-2026-23206 affects the Linux kernel dpaa2-switch driver where zero interfaces (num_ifs == 0) caused a NULL-like ZERO_SIZE_PTR allocation and a kernel panic during probe. The issue stems from allocating arrays with kcalloc() using ethsw->sw_attr.num_ifs and dereferencing ports[0] i...

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 ...
