Summary
mlxsw: spectrum_acl_tcam: Fix NULL pointer dereference in error path
Details

In the Linux kernel, the following vulnerability has been resolved:

mlxsw: spectrumacltcam: Fix NULL pointer dereference in error path

When calling mlxswspacltcamregion_destroy() from an error path after failing to attach the region to an ACL group, we hit a NULL pointer dereference upon 'region->group->tcam' [1].

Fix by retrieving the 'tcam' pointer using mlxswspacltotcam().
