Title
wifi: rtw88: Use devm_kmemdup() in rtw_set_supported_band()
Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: Use devm_kmemdup() in rtw_set_supported_band() Simplify the code by using device managed memory allocations. This also fixes a memory leak in rtw_register_hw(). The supported bands were not freed in the error path. Copied from commit 145df52a8671 ("wifi: rtw89: Convert rtw89_core_set_supported_band to use devm_*").

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
