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,...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: rapidio: Fix an API misuse when rioaddnet fails. rioaddnet calls deviceregister, and it fails when deviceregister does. Therefore, putdevice should be used instead of kfree. Also, add "mport-net = NULL;" to avoid a...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: rapidio: Replace riofreenet with kfree in rioscanallocnet. When the idtab allocation fails, the network is not yet registered with rioaddnet. Therefore, calling kfreenet is sufficient to release the memory. Set mport-net to NULL ...

CVE-2026-43295

In the Linux kernel, the following vulnerability has been resolved: rapidio: replace riofreenet with kfree in rioscanallocnet When idtab allocation fails, net is not registered with rioaddnet yet, so kfreenet is sufficient to release the memory. Set mport-net to NULL to avoid dangling pointer...

CVE-2026-43295 rapidio: replace rio_free_net() with kfree() in rio_scan_alloc_net()

In the Linux kernel, the following vulnerability has been resolved: rapidio: replace riofreenet with kfree in rioscanallocnet When idtab allocation fails, net is not registered with rioaddnet yet, so kfreenet is sufficient to release the memory. Set mport-net to NULL to avoid dangling pointer...
