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...

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...
