Description OSIDB Bzimport 2026-05-06 13:10:27 UTC 
In the Linux kernel, the following vulnerability has been resolved:

mux: mmio: fix regmap leak on probe failure

The mmio regmap that may be allocated during probe is never freed.

Switch to using the device managed allocator so that the regmap is
released on probe failures (e.g. probe deferral) and on driver unbind.
