In the Linux kernel, the following vulnerability has been resolved: rpmsg: char: Fix use-after-free on probe error path rpmsg_chrdev_probe() stores the newly allocated eptdev in the default endpoint's priv pointer before calling rpmsg_chrdev_eptdev_add(). If rpmsg_chrdev_eptdev_add() then fails, its error path frees eptdev while the default endpoint may still dispatch callbacks with the stale priv pointer. Avoid publishing eptdev through the default endpoint until rpmsg_chrdev_eptdev_add() succeeds. Messages received before the priv pointer is published should be ignored by rpmsg_ept_cb(). Flow-control updates can hit rpmsg_ept_flow_cb() in the same window, so make both callbacks return success when priv is NULL.

An update of the linux package has been released.

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-4723 advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - rpmsg: char: Fix use-after-free on probe error path rpmsg_chrdev_probe() stores the newly allocated eptdev     in the default endpoint's priv pointer before calling rpmsg_chrdev_eptdev_add(). If     rpmsg_chrdev_eptdev_add() then fails, its error path frees eptdev while the default endpoint may still     dispatch callbacks with the stale priv pointer. Avoid publishing eptdev through the default endpoint until     rpmsg_chrdev_eptdev_add() succeeds. Messages received before the priv pointer is published should be     ignored by rpmsg_ept_cb(). Flow-control updates can hit rpmsg_ept_flow_cb() in the same window, so make     both callbacks return success when priv is NULL. (CVE-2026-63797)

Note that Nessus relies on the presence of the package as reported by the vendor.
