"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Fix out-of-bounds access in 'dcn21_link_encoder_create'\n\nAn issue was identified in the dcn21_link_encoder_create function where\nan out-of-bounds access could occur when the hpd_source index was used\nto reference the link_enc_hpd_regs array. This array has a fixed size\nand the index was not being checked against the array's bounds before\naccessing it.\n\nThis fix adds a conditional check to ensure that the hpd_source index is\nwithin the valid range of the link_enc_hpd_regs array. If the index is\nout of bounds, the function now returns NULL to prevent undefined\nbehavior.\n\nReferences:\n\n[ 65.920507] ------------[ cut here ]------------\n[ 65.920510] UBSAN: array-index-out-of-bounds in drivers/gpu/drm/amd/amdgpu/../display/dc/resource/dcn21/dcn21_resource.c:1312:29\n[ 65.920519] index 7 is out of range for type 'dcn10_link_enc_hpd_registers [5]'\n[ 65.920523] CPU: 3 PID: 1178 Comm: modprobe Tainted: G OE 6.8.0-cleanershaderfeatureresetasdntipmi200nv2132 #13\n[ 65.920525] Hardware name: AMD Majolica-RN/Majolica-RN, BIOS WMJ0429N_Weekly_20_04_2 04/29/2020\n[ 65.920527] Call Trace:\n[ 65.920529] <TASK>\n[ 65.920532] dump_stack_lvl+0x48/0x70\n[ 65.920541] dump_stack+0x10/0x20\n[ 65.920543] __ubsan_handle_out_of_bounds+0xa2/0xe0\n[ 65.920549] dcn21_link_encoder_create+0xd9/0x140 [amdgpu]\n[ 65.921009] link_create+0x6d3/0xed0 [amdgpu]\n[ 65.921355] create_links+0x18a/0x4e0 [amdgpu]\n[ 65.921679] dc_create+0x360/0x720 [amdgpu]\n[ 65.921999] ? dmi_matches+0xa0/0x220\n[ 65.922004] amdgpu_dm_init+0x2b6/0x2c90 [amdgpu]\n[ 65.922342] ? console_unlock+0x77/0x120\n[ 65.922348] ? dev_printk_emit+0x86/0xb0\n[ 65.922354] dm_hw_init+0x15/0x40 [amdgpu]\n[ 65.922686] amdgpu_device_init+0x26a8/0x33a0 [amdgpu]\n[ 65.922921] amdgpu_driver_load_kms+0x1b/0xa0 [amdgpu]\n[ 65.923087] amdgpu_pci_probe+0x1b7/0x630 [amdgpu]\n[ 65.923087] local_pci_probe+0x4b/0xb0\n[ 65.923087] pci_device_probe+0xc8/0x280\n[ 65.923087] really_probe+0x187/0x300\n[ 65.923087] __driver_probe_device+0x85/0x130\n[ 65.923087] driver_probe_device+0x24/0x110\n[ 65.923087] __driver_attach+0xac/0x1d0\n[ 65.923087] ? __pfx___driver_attach+0x10/0x10\n[ 65.923087] bus_for_each_dev+0x7d/0xd0\n[ 65.923087] driver_attach+0x1e/0x30\n[ 65.923087] bus_add_driver+0xf2/0x200\n[ 65.923087] driver_register+0x64/0x130\n[ 65.923087] ? __pfx_amdgpu_init+0x10/0x10 [amdgpu]\n[ 65.923087] __pci_register_driver+0x61/0x70\n[ 65.923087] amdgpu_init+0x7d/0xff0 [amdgpu]\n[ 65.923087] do_one_initcall+0x49/0x310\n[ 65.923087] ? kmalloc_trace+0x136/0x360\n[ 65.923087] do_init_module+0x6a/0x270\n[ 65.923087] load_module+0x1fce/0x23a0\n[ 65.923087] init_module_from_file+0x9c/0xe0\n[ 65.923087] ? init_module_from_file+0x9c/0xe0\n[ 65.923087] idempotent_init_module+0x179/0x230\n[ 65.923087] __x64_sys_finit_module+0x5d/0xa0\n[ 65.923087] do_syscall_64+0x76/0x120\n[ 65.923087] entry_SYSCALL_64_after_hwframe+0x6e/0x76\n[ 65.923087] RIP: 0033:0x7f2d80f1e88d\n[ 65.923087] Code: 5b 41 5c c3 66 0f 1f 84 00 00 00 00 00 f3 0f 1e fa 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d 73 b5 0f 00 f7 d8 64 89 01 48\n[ 65.923087] RSP: 002b:00007ffc7bc1aa78 EFLAGS: 00000246 ORIG_RAX: 0000000000000139\n[ 65.923087] RAX: ffffffffffffffda RBX: 0000564c9c1db130 RCX: 00007f2d80f1e88d\n[ 65.923087] RDX: 0000000000000000 RSI: 0000564c9c1e5480 RDI: 000000000000000f\n[ 65.923087] RBP: 0000000000040000 R08: 0000000000000000 R09: 0000000000000002\n[ 65.923087] R10: 000000000000000f R11: 0000000000000246 R12: 0000564c9c1e5480\n[ 65.923087] R13: 0000564c9c1db260 R14: 0000000000000000 R15: 0000564c9c1e54b0\n[ 65.923087] </TASK>\n[ 65.923927] ---[ end trace ]---"
