"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rtw89: avoid NULL dereference when RX problematic packet on unsupported 6 GHz band\n\nWith a quite rare chance, RX report might be problematic to make SW think\na packet is received on 6 GHz band even if the chip does not support 6 GHz\nband actually. Since SW won't initialize stuffs for unsupported bands, NULL\ndereference will happen then in the sequence, rtw89_vif_rx_stats_iter() ->\nrtw89_core_cancel_6ghz_probe_tx(). So, add a check to avoid it.\n\nThe following is a crash log for this case.\n\n BUG: kernel NULL pointer dereference, address: 0000000000000032\n #PF: supervisor read access in kernel mode\n #PF: error_code(0x0000) - not-present page\n PGD 0 P4D 0\n Oops: 0000 [#1] PREEMPT SMP NOPTI\n CPU: 1 PID: 1907 Comm: irq/131-rtw89_p Tainted: G U 6.6.56-05896-g89f5fb0eb30b #1 (HASH:1400 4)\n Hardware name: Google Telith/Telith, BIOS Google_Telith.15217.747.0 11/12/2024\n RIP: 0010:rtw89_vif_rx_stats_iter+0xd2/0x310 [rtw89_core]\n Code: 4c 89 7d c8 48 89 55 c0 49 8d 44 24 02 48 89 45 b8 45 31 ff eb 11\n 41 c6 45 3a 01 41 b7 01 4d 8b 6d 00 4d 39 f5 74 42 8b 43 10 <41> 33 45\n 32 0f b7 4b 14 66 41 33 4d 36 0f b7 c9 09 c1 74 d8 4d 85\n RSP: 0018:ffff9f3080138ca0 EFLAGS: 00010246\n RAX: 00000000b8bf5770 RBX: ffff91b5e8c639c0 RCX: 0000000000000011\n RDX: ffff91b582de1be8 RSI: 0000000000000000 RDI: ffff91b5e8c639e6\n RBP: ffff9f3080138d00 R08: 0000000000000000 R09: 0000000000000000\n R10: ffff91b59de70000 R11: ffffffffc069be50 R12: ffff91b5e8c639e4\n R13: 0000000000000000 R14: ffff91b5828020b8 R15: 0000000000000000\n FS: 0000000000000000(0000) GS:ffff91b8efa40000(0000) knlGS:0000000000000000\n CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n CR2: 0000000000000032 CR3: 00000002bf838000 CR4: 0000000000750ee0\n PKRU: 55555554\n Call Trace:\n <IRQ>\n ? __die_body+0x68/0xb0\n ? page_fault_oops+0x379/0x3e0\n ? exc_page_fault+0x4f/0xa0\n ? asm_exc_page_fault+0x22/0x30\n ? __pfx_rtw89_vif_rx_stats_iter+0x10/0x10 [rtw89_core (HASH:1400 5)]\n ? rtw89_vif_rx_stats_iter+0xd2/0x310 [rtw89_core (HASH:1400 5)]\n __iterate_interfaces+0x59/0x110 [mac80211 (HASH:1400 6)]\n ? __pfx_rtw89_vif_rx_stats_iter+0x10/0x10 [rtw89_core (HASH:1400 5)]\n ? __pfx_rtw89_vif_rx_stats_iter+0x10/0x10 [rtw89_core (HASH:1400 5)]\n ieee80211_iterate_active_interfaces_atomic+0x36/0x50 [mac80211 (HASH:1400 6)]\n rtw89_core_rx_to_mac80211+0xfd/0x1b0 [rtw89_core (HASH:1400 5)]\n rtw89_core_rx+0x43a/0x980 [rtw89_core (HASH:1400 5)]"
