CVSS: 8.3EPSS: 0%CPEs: 26EXPL: 13CVE-2021-22555 – Heap Out-Of-Bounds Write in Netfilter IP6T_SO_SET_REPLACE
https://notcve.org/view.php?id=CVE-2021-22555
A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c. This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name space En el archivo net/netfilter/x_tables.c se ha detectado una escritura fuera de límites en la pila que afecta a Linux desde la versión 2.6.19-rc1. Esto permite a un atacante alcanzar privilegios o causar una denegación de servicio (por medio de corrupción de la memoria de la pila) mediante el espacio de nombres de usuario A flaw was discovered in processing setsockopt IPT_SO_SET_REPLACE (or IP6T_SO_SET_REPLACE) for 32 bit processes on 64 bit systems. This flaw will allow local user to gain privileges or cause a DoS through user name space. This action is usually restricted to root-privileged users but can also be leveraged if the kernel is compiled with CONFIG_USER_NS and CONFIG_NET_NS and the user is granted elevated privileges. • https://www.exploit-db.com/exploits/50135 https://github.com/xyjl-ly/CVE-2021-22555-Exploit https://github.com/veritas501/CVE-2021-22555-PipeVersion https://github.com/pashayogi/CVE-2021-22555 https://github.com/tukru/CVE-2021-22555 https://github.com/letsr00t/CVE-2021-22555 https://github.com/letsr00t/-2021-LOCALROOT-CVE-2021-22555 https://github.com/daletoniris/CVE-2021-22555-esc-priv http://packetstormsecurity.com/files/163528/Linux-Kernel-Netfilter-Heap-Out-Of-Bounds-Write.h • CWE-787: Out-of-bounds Write •
