CVE-2024-40910

A vulnerability was found in the Linux kernel, related to the ax25 protocol. This issue can cause a reference count imbalance during the handling of inbound connections. The ax25_release() function incorrectly decrements the reference count of the associated ax.25 device using netdev_put() without a corresponding netdev_hold() in the connection acceptance path. This imbalance can lead to kernel crashes and memory errors, indicated by messages such as refcount_t: decrement hit 0; leaking memory and refcount_t: underflow; use-after-free.

Red Hat Enterprise Linux is not vulnerable to this CVE, as it does not affect the versions or configurations of the Linux kernel used in its distributions.
