CVSS: 7.5EPSS: 0%CPEs: 44EXPL: 0CVE-2021-45485 – kernel: information leak in the IPv6 implementation
https://notcve.org/view.php?id=CVE-2021-45485
In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses. En la implementación de IPv6 en el kernel de Linux versiones anteriores a 5.13.3, el archivo net/ipv6/output_core.c presenta un filtrado de información debido a determinado uso de una tabla hash que, aunque es grande, no considera apropiadamente que atacantes basados en IPv6 pueden elegir típicamente entre muchas direcciones de origen IPv6 An information leak flaw was found in the Linux kernel’s IPv6 implementation in the __ipv6_select_ident in net/ipv6/output_core.c function. The use of a small hash table in IP ID generation allows a remote attacker to reveal sensitive information. • https://arxiv.org/pdf/2112.09604.pdf https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.13.3 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=62f20e068ccc50d6ab66fdb72ba90da2b9418c99 https://security.netapp.com/advisory/ntap-20220121-0001 https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2021-45485 https://bugzilla.redhat.com/show_bug.cgi?id=2039911 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
CVSS: 8.3EPSS: 0%CPEs: 26EXPL: 14CVE-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 •
