CVE-2026-90319

CVE-2026-90319 affects the RapidIO (rio) subsystem in the Linux kernel . The root cause is a use-after-free / double-free bug: when rio_add_net() fails during device registration, rio_scan_alloc_net() releases the allocated rio_net object via put_device(), but the mport->net pointer is left da...

CVE-2026-90319 rapidio: clear mport->net when rio_add_net() fails

In the Linux kernel, the following vulnerability has been resolved: rapidio: clear mport-net when rioaddnet fails rioallocnet stores the newly allocated rionet in mport-net before rioscanallocnet registers the device. If rioaddnet fails, rioscanallocnet drops the device reference with putdevice,...
