UBUNTU-CVE-2024-26752

In the Linux kernel, the following vulnerability has been resolved: l2tp: pass correct message length to ip6appenddata l2tpip6sendmsg needs to avoid accounting for the transport header twice when splicing more data into an already partially-occupied skbuff. To manage this, we check whether the...

CVE-2024-26641

In the Linux kernel, the following vulnerability has been resolved: ip6tunnel: make sure to pull inner header in ip6tnlrcv syzbot found ip6tnlrcv could access unitiliazed data 1. Call pskbinetmaypull to fix this, and initialize ipv6h variable after this call as it can change skb-head. 1 BUG: KMSA...

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...

CVE-2023-52527

CVE-2023-52527 involves the Linux kernel IPv4/IPv6 path: the handling of transhdrlen in __ip{,6}_append_data() could inflate the length when a packet is only partially filled (e.g., after MSG_MORE), risking duplicate transport header accounting. The issue can arise when splicing into an L2TP sock...

SUSE CVE-2013-2232

The ip6skdstcheck function in net/ipv6/ip6output.c in the Linux kernel before 3.10 allows local users to cause a denial of service system crash by using an AFINET6 socket for a connection to an IPv4 interface...

SUSE CVE-2013-3230

The l2tpip6recvmsg function in net/l2tp/l2tpip6.c in the Linux kernel before 3.9-rc7 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel stack memory via a crafted recvmsg or recvfrom system call...
