kernel: tunnels: fix out of bounds access when building IPv6 PMTU error

A flaw was found in the Linux kernel. This issue occurs due to the improper handling of non-linear skbs socket buffers when calculating checksums for ICMPv6 PMTU error messages. This vulnerability can lead to out-of-bounds access, potentially causing memory corruption or crashes...

kernel: ipv6: fix race condition between ipv6_get_ifaddr and ipv6_del_addr

This CVE addresses a race condition in the Linux kernel's IPv6 subsystem, specifically between the ipv6getifaddr and ipv6deladdr functions. This race condition can lead to use-after-free scenarios, potentially causing system instability or crashes...

The IPv6 implementation in the Linux kernel before 6.3 has a net/ipv6/route.c max_size threshold that can be consumed easily e.g. leading to a denial of service (network is unreachable errors) when IPv6 packets are sent in a loop via a raw socket.

This CVE addresses a race condition in the Linux kernel's IPv6 subsystem, specifically between the ipv6getifaddr and ipv6deladdr functions. This race condition can lead to use-after-free scenarios, potentially causing system instability or crashes...

The vulnerability of the __fib6_rule_action() function in the Linux operating system’s IPv6 kernel implementation allows a hacker to induce a service failure.

The vulnerability of the fib6ruleaction function in the net/ipv6/fib6rules.c module of the Linux operating system’s IPv6 kernel implementation is related to the assignment of a null pointer. Exploiting this vulnerability could allow an attacker to cause a service failure remotely...

SUSE CVE-2021-47572

In the Linux kernel, the following vulnerability has been resolved: net: nexthop: fix null pointer dereference when IPv6 is not enabled When we try to add an IPv6 nexthop and IPv6 is not enabled !CONFIGIPV6 we'll hit a NULL pointer dereference1 in the error path of nhcreateipv6 due to calling...

SUSE CVE-2021-47291

In the Linux kernel, the following vulnerability has been resolved: ipv6: fix another slab-out-of-bounds in fib6nhflushexceptions While running the self-tests on a KASAN enabled kernel, I observed a slab-out-of-bounds splat very similar to the one reported in commit 821bbf79fe46 "ipv6: Fix KASAN:...

kernel: ICMPv6 “Packet Too Big” packets force a DoS of the Linux kernel by forcing 100% CPU

A flaw in the routing table size was found in the ICMPv6 handling of "Packet Too Big". The size of the routing table is regulated by periodic garbage collection. However, with "Packet Too Big Messages" it is possible to exceed the routing table size and garbage collector threshold. A user located...

DEBIAN-CVE-2021-47109

In the Linux kernel, the following vulnerability has been resolved: neighbour: allow NUDNOARP entries to be forced GCed IFFPOINTOPOINT interfaces use NUDNOARP entries for IPv6. It's possible to fill up the neighbour table with enough entries that it will overflow for valid connections after that...

edk2: Buffer overflow when processing DNS Servers option in a DHCPv6 Advertise message

A security weakness was identified in EDK2, the open-source reference implementation of the UEFI specification, revealing a buffer overflow vulnerability. This vulnerability enables an unauthorized attacker within proximity on the network to transmit a specifically crafted DHCPv6 Advertise messag...

Important: edk2
