If color_matching is not\nfound, config_group_find_item() returns NULL. The code then jumps to\nout_put_cm, where it calls config_item_put(color_matching);. If\ncolor_matching is NULL, this will dereference a null pointer, leading to a\ncrash.\n\n[ 2.746440] Unable to handle kernel NULL pointer dereference at virtual address 000000000000008c\n[ 2.756273] Mem abort info:\n[ 2.760080] ESR = 0x0000000096000005\n[ 2.764872] EC = 0x25: DABT (current EL), IL = 32 bits\n[ 2.771068] SET = 0, FnV = 0\n[ 2.771069] EA = 0, S1PTW = 0\n[ 2.771070] FSC = 0x05: level 1 translation fault\n[ 2.771071] Data abort info:\n[ 2.771072] ISV = 0, ISS = 0x00000005, ISS2 = 0x00000000\n[ 2.771073] CM = 0, WnR = 0, TnD = 0, TagAccess = 0\n[ 2.771074] GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0\n[ 2.771075] user pgtable: 4k pages, 39-bit VAs, pgdp=00000000a3e59000\n[ 2.771077] [000000000000008c] pgd=0000000000000000, p4d=0000000000000000, pud=0000000000000000\n[ 2.771081] Internal error: Oops: 0000000096000005 [#1] PREEMPT SMP\n[ 2.771084] Dumping ftrace buffer:\n[ 2.771085] (ftrace buffer empty)\n[ 2.771138] CPU: 7 PID: 486 Comm: ln Tainted: G W E 6.6.58-android15\n[ 2.771139] Hardware name: Qualcomm Technologies, Inc.
