CVE-2026-23090
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
slimbus: core: fix device reference leak on report present
Slimbus devices can be allocated dynamically upon reception of report-present messages.
Make sure to drop the reference taken when looking up already registered devices.
Note that this requires taking an extra reference in case the device has not yet been registered and has to be allocated.
