The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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. (CVE-2022-49326)
