Title
ext4: fix memory leaks in ext4_fname_{setup_filename,prepare_lookup}
Summary
In the Linux kernel, the following vulnerability has been resolved: ext4: fix memory leaks in ext4_fname_{setup_filename,prepare_lookup} If the filename casefolding fails, we'll be leaking memory from the fscrypt_name struct, namely from the 'crypto_buf.name' member. Make sure we free it in the error path on both ext4_fname_setup_filename() and ext4_fname_prepare_lookup() functions.

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.
