Description
In the Linux kernel, the following vulnerability has been resolved:
net: bridge: mst: pass vlan group directly to br_mst_vlan_set_state
Pass the already obtained vlan group pointer to br_mst_vlan_set_state()
instead of dereferencing it again. Each caller has already correctly
dereferenced it for their context. This change is required for the
following suspicious RCU dereference fix. No functional changes
intended.
Affected configurations
• linux linux kernel (>= 6.1.93 < 6.1.95)
• linux linux kernel (>= 6.6.33 < 6.6.35)
• linux linux kernel (>= 6.8.12 < 6.9)
