Title
rtl818x: Prevent using not initialized queues
Summary
In the Linux kernel, the following vulnerability has been resolved: rtl818x: Prevent using not initialized queues Using not existing queues can panic the kernel with rtl8180/rtl8185 cards. Ignore the skb priority for those cards, they only have one tx queue. Pierre Asselin (pa@panix.com) reported the kernel crash in the Gentoo forum: https://forums.gentoo.org/viewtopic-t-1147832-postdays-0-postorder-asc-start-25.html He also confirmed that this patch fixes the issue. In summary this happened: After updating wpa_supplicant from 2.9 to 2.10 the kernel crashed with a "divide error: 0000" when connecting to an AP. Control port tx now tries to use IEEE80211_AC_VO for the priority, which wpa_supplicants starts to use in 2.10. Since only the rtl8187se part of the driver supports QoS, the priority of the skb is set to IEEE80211_AC_BE (2) by mac80211 for rtl8180/rtl8185 cards. rtl8180 is then unconditionally reading out the priority and finally crashes on drivers/net/wireless/realtek/rtl818x/rtl8180/dev.c line 544 without this patch: idx = (ring->idx + skb_queue_len(&ring->queue)) % ring->entries "ring->entries" is zero for rtl8180/rtl8185 cards, tx_ring[2] never got initialized.

Pierre\\nAsselin (pa@panix.com) reported the kernel crash in the Gentoo forum:\\n\\nhttps://forums.gentoo.org/viewtopic-t-1147832-postdays-0-postorder-asc-start-25.html\\n\\nHe also confirmed that this patch fixes the issue. In summary this happened:\\n\\nAfter updating wpa_supplicant from 2.9 to 2.10 the kernel crashed with a\\n\\\"divide error: 0000\\\" when connecting to an AP. Control port tx now tries to\\nuse IEEE80211_AC_VO for the priority, which wpa_supplicants starts to use in\\n2.10.\\n\\nSince only the rtl8187se part of the driver supports QoS, the priority\\nof the skb is set to IEEE80211_AC_BE (2) by mac80211 for rtl8180/rtl8185\\ncards.\\n\\nrtl8180 is then unconditionally reading out the priority and finally crashes on\\ndrivers/net/wireless/realtek/rtl818x/rtl8180/dev.c line 544 without this\\npatch:\\n\\tidx = (ring-\u003eidx + skb_queue_len(\u0026ring-\u003equeue)) % ring-\u003eentries\\n\\n\\\"ring-\u003eentries\\\" is zero for rtl8180/rtl8185 cards, tx_ring[2] never got\\ninitialized.\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"4.9.318\", \"versionStartIncluding\": \"3.15\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"4.14.283\", \"versionStartIncluding\": \"3.15\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"4.19.247\", \"versionStartIncluding\": \"3.15\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.4.198\", \"versionStartIncluding\": \"3.15\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.10.121\", \"versionStartIncluding\": \"3.15\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.15.46\", \"versionStartIncluding\": \"3.15\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.17.14\", \"versionStartIncluding\": \"3.15\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.18.3\", \"versionStartIncluding\": \"3.15\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.19\", \"versionStartIncluding\": \"3.15\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2026-05-11T18:57:31.977Z\"}}}",
