SUSE CVE-2014-9717

fs/namespace.c in the Linux kernel before 4.0.2 processes MNTDETACH umount2 system calls without verifying that the MNTLOCKED flag is unset, which allows local users to bypass intended access restrictions and navigate to filesystem locations beneath a mount by calling umount2 within a user...

SUSE CVE-2017-0920

GitLab Community and Enterprise Editions before 10.1.6, 10.2.6, and 10.3.4 are vulnerable to an authorization bypass issue in the Projects::MergeRequests::CreationsController component resulting in an attacker to see every project name and their respective namespace on a GitLab instance...

SUSE CVE-2017-11610

The XML-RPC server in supervisor before 3.0.1, 3.1.x before 3.1.4, 3.2.x before 3.2.4, and 3.3.x before 3.3.3 allows remote authenticated users to execute arbitrary commands via a crafted XML-RPC request, related to nested supervisord namespace lookups...

SUSE CVE-2017-15129

A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function getnetnsbyid in net/core/netnamespace.c does not check for the net::count value after it has found a peer network in netnsids idr, which could lead to double free and memory...

SUSE CVE-2017-17450

net/netfilter/xtosf.c in the Linux kernel through 4.14.4 does not require the CAPNETADMIN capability for addcallback and removecallback operations, which allows local users to bypass intended access restrictions because the xtosffingers data structure is shared across all net namespaces...

SUSE CVE-2017-17449

The netlinkdelivertapskb function in net/netlink/afnetlink.c in the Linux kernel through 4.14.4, when CONFIGNLMON is enabled, does not restrict observations of Netlink messages to a single net namespace, which allows local users to obtain sensitive information by leveraging the CAPNETADMIN...

SUSE CVE-2017-17448

net/netfilter/nfnetlinkcthelper.c in the Linux kernel through 4.14.4 does not require the CAPNETADMIN capability for new, get, and del operations, which allows local users to bypass intended access restrictions because the nfnlcthelperlist data structure is shared across all net namespaces...

SUSE CVE-2017-1000111

Linux kernel: heap out-of-bounds in AFPACKET sockets. This new issue is analogous to previously disclosed CVE-2016-8655. In both cases, a socket option that changes socket state may race with safety checks in packetsetring. Previously with PACKETVERSION. This time with PACKETRESERVE. The solution...

SUSE CVE-2018-6559

The Linux kernel, as used in Ubuntu 18.04 LTS and Ubuntu 18.10, allows local users to obtain names of files in which they would not normally be able to access via an overlayfs mount inside of a user namespace...

SUSE CVE-2018-16884

A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bcsvcprocess use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and ...

SUSE CVE-2018-18955

In the Linux kernel 4.15.x through 4.19.x before 4.19.2, mapwrite in kernel/usernamespace.c allows privilege escalation because it mishandles nested user namespaces with more than 5 UID or GID ranges. A user who has CAPSYSADMIN in an affected user namespace can bypass access controls on resources...

SUSE CVE-2019-20794

An issue was discovered in the Linux kernel 4.18 through 5.6.11 when unprivileged user namespaces are allowed. A user can create their own PID namespace, and mount a FUSE filesystem. Upon interaction with this FUSE filesystem, if the userspace component is terminated via a kill of the PID...

SUSE CVE-2020-5291

Bubblewrap bwrap before version 0.4.1, if installed in setuid mode and the kernel supports unprivileged user namespaces, then the bwrap --userns2 option can be used to make the setuid process keep running as root while being traceable. This can in turn be used to gain root permissions. Note that...

SUSE CVE-2020-16120

Overlayfs did not properly perform permission checking when copying up files in an overlayfs and could be exploited from within a user namespace, if, for example, unprivileged user namespaces were allowed. It was possible to have a file not readable by an unprivileged user to be copied to a...

SUSE CVE-2021-3493

The overlayfs implementation in the linux kernel did not properly validate with respect to user namespaces the setting of file capabilities on files in an underlying file system. Due to the combination of unprivileged user namespaces along with a patch carried in the Ubuntu kernel to allow...

SUSE CVE-2022-1055

A use-after-free exists in the Linux Kernel in tcnewtfilter that could allow a local attacker to gain privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5...

SUSE CVE-2022-2837

A flaw was found in coreDNS. This flaw allows a malicious user to redirect traffic intended for external top-level domains TLD to a pod they control by creating projects and namespaces that match the TLD...

SUSE CVE-2022-24122

kernel/ucount.c in the Linux kernel 5.14 through 5.16.4, when unprivileged user namespaces are enabled, allows a use-after-free and privilege escalation because a ucounts object can outlive its namespace...

SUSE CVE-2022-32250

net/netfilter/nftablesapi.c in the Linux kernel through 5.18.1 allows a local user able to create user/net namespaces to escalate privileges to root because an incorrect NFTSTATEFULEXPR check leads to a use-after-free...

CVE-2023-23455

A denial of service flaw was found in atmtcenqueue in net/sched/schatm.c in the Linux kernel. This issue may allow a local attacker to cause a denial of service due to type confusion. Non-negative numbers could indicate a TCACTSHOT condition rather than valid classification results. Mitigation Th...
