CVE-2022-42721

Un error de administración de listas en el manejo de BSS en la pila mac80211 en el kernel de Linux versiones 5.1 hasta 5.19.14, podría ser usado por atacantes locales (capaces de inyectar tramas WLAN) para corromper una lista enlazada y, a su vez, ejecutar potencialmente código

A list corruption flaw was found in cfg80211_add_nontrans_list in the net/wireless/scan.c function in the Linux kernel. This flaw could lead to a denial of service.

David Bouman discovered that the netfilter subsystem in the Linux kernel did not properly validate passed user register indices. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. David Bouman and Billy Jheng Bing Jhong discovered that a race condition existed in the io_uring subsystem in the Linux kernel, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. Various other issues were also addressed.
