This also fix the issue reported\nin [1].\n\nThe crash occurs when this function is triggered before the station is\nfully initialized. The call trace shows a page fault at\nmt7925_sta_set_decap_offload() due to accessing resources when msta->vif\nis NULL.\n\nFix this by adding an early return if msta->vif is NULL and also check\nwcid.sta is ready. This ensures we only proceed with decap offload\nconfiguration when the station's state is properly initialized.\n\n[14739.655703] Unable to handle kernel paging request at virtual address ffffffffffffffa0\n[14739.811820] CPU: 0 UID: 0 PID: 895854 Comm: hostapd Tainted: G\n[14739.821394] Tainted: [C]=CRAP, [O]=OOT_MODULE\n[14739.825746] Hardware name: Raspberry Pi 4 Model B Rev 1.1 (DT)\n[14739.831577] pstate: 60000005 (nZCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--)\n[14739.838538] pc : mt7925_sta_set_decap_offload+0xc0/0x1b8 [mt7925_common]\n[14739.845271] lr : mt7925_sta_set_decap_offload+0x58/0x1b8 [mt7925_common]\n[14739.851985] sp : ffffffc085efb500\n[14739.855295] x29: ffffffc085efb500 x28: 0000000000000000 x27: ffffff807803a158\n[14739.862436] x26: ffffff8041ececb8 x25: 0000000000000001 x24: 0000000000000001\n[14739.869577] x23: 0000000000000001 x22: 0000000000000008 x21: ffffff8041ecea88\n[14739.876715] x20: ffffff8041c19ca0 x19: ffffff8078031fe0 x18: 0000000000000000\n[14739.883853] x17: 0000000000000000 x16: ffffffe2aeac1110 x15: 000000559da48080\n[14739.890991] x14: 0000000000000001 x13: 0000000000000000 x12: 0000000000000000\n[14739.898130] x11: 0a10020001008e88 x10: 0000000000001a50 x9 : ffffffe26457bfa0\n[14739.905269] x8 : ffffff8042013bb0 x7 : ffffff807fb6cbf8 x6 : dead000000000100\n[14739.912407] x5 : dead000000000122 x4 : ffffff80780326c8 x3 : 0000000000000000\n[14739.919546] x2 : 0000000000000000 x1 : 0000000000000000 x0 : ffffff8041ececb8\n[14739.926686] Call trace:\n[14739.929130] mt7925_sta_set_decap_offload+0xc0/0x1b8 [mt7925_common]\n[14739.935505] ieee80211_check_fast_rx+0x19c/0x510 [mac80211]\n[14739.941344] _sta_info_move_state+0xe4/0x510 [mac80211]\n[14739.946860] sta_info_move_state+0x1c/0x30 [mac80211]\n[14739.952116] sta_apply_auth_flags.constprop.0+0x90/0x1b0 [mac80211]\n[14739.958708] sta_apply_parameters+0x234/0x5e0 [mac80211]\n[14739.964332] ieee80211_add_station+0xdc/0x190 [mac80211]\n[14739.969950] nl80211_new_station+0x46c/0x670 [cfg80211]\n[14739.975516] genl_family_rcv_msg_doit+0xdc/0x150\n[14739.980158] genl_rcv_msg+0x218/0x298\n[14739.983830] netlink_rcv_skb+0x64/0x138\n[14739.987670] genl_rcv+0x40/0x60\n[14739.990816] netlink_unicast+0x314/0x380\n[14739.994742] netlink_sendmsg+0x198/0x3f0\n[14739.998664] __sock_sendmsg+0x64/0xc0\n[14740.002324] ____sys_sendmsg+0x260/0x298\n[14740.006242] ___sys_sendmsg+0xb4/0x110" } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/net/wireless/mediatek/mt76/mt7925/main.c" ], "versions": [ { "version": "b859ad65309a5f1654e8b284de582831fc88e2d8", "lessThan": "9b50874f297fcc62adc7396f35209878e51010b0", "status": "affected", "versionType": "git" }, { "version": "b859ad65309a5f1654e8b284de582831fc88e2d8", "lessThan": "91c3dec2453b3742e8f666957b99945edc30577f", "status": "affected", "versionType": "git" }, { "version": "b859ad65309a5f1654e8b284de582831fc88e2d8", "lessThan": "35ad47c0b3da04b00b19a8b9ed5632e2f2520472", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/net/wireless/mediatek/mt76/mt7925/main.c" ], "versions": [ { "version": "6.11", "status": "affected" }, { "version": "0", "lessThan": "6.11", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.39", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.15.7", "lessThanOrEqual": "6.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.16", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.11", "versionEndExcluding": "6.12.39" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.11", "versionEndExcluding": "6.15.7" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.11", "versionEndExcluding": "6.16" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/9b50874f297fcc62adc7396f35209878e51010b0" }, { "url": "https://git.kernel.org/stable/c/91c3dec2453b3742e8f666957b99945edc30577f" }, { "url": "https://git.kernel.org/stable/c/35ad47c0b3da04b00b19a8b9ed5632e2f2520472" } ], "title": "wifi: mt76: mt7925: prevent NULL pointer dereference in mt7925_sta_set_decap_offload()", "x_generator": { "engine": "bippy-1.2.0" } } } }
