Ubuntu.comUB:CVE-2024-38554CVE-2024-38554
In the Linux kernel, the following vulnerability has been resolved: ax25:
Fix reference count leak issue of net_device There is a reference count
leak issue of the object “net_device” in ax25_dev_device_down(). When the
ax25 device is shutting down, the ax25_dev_device_down() drops the
reference count of net_device one or zero times depending on if we goto
unlock_put or not, which will cause memory leak. In order to solve the
above issue, decrease the reference count of net_device after dev->ax25_ptr
is set to null.
