CVE-2021-42327 3 Fedoraproject, Linux, Netapp 18 Fedora, Linux Kernel, H300e and 15 more 2024-11-21 4.6 MEDIUM 6.7 MEDIUM
dp_link_settings_write in drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_debugfs.c in the Linux kernel through 5.14.14 allows a heap-based buffer overflow by an attacker who can write a string to the AMD GPU display drivers debug filesystem. There are no checks on size within parse_write_buffer_into_params when it uses the size of copy_from_user to copy a userspace buffer into a 40-byte heap buffer.
CVE-2021-42252 2 Linux, Netapp 19 Linux Kernel, H300e, H300e Firmware and 16 more 2024-11-21 4.6 MEDIUM 7.8 HIGH
An issue was discovered in aspeed_lpc_ctrl_mmap in drivers/soc/aspeed/aspeed-lpc-ctrl.c in the Linux kernel before 5.14.6. Local attackers able to access the Aspeed LPC control interface could overwrite memory in the kernel and potentially execute privileges, aka CID-b49a0e69a7b1. This occurs because a certain comparison uses values that are not memory sizes.
CVE-2021-42083 3 Linux, Microsoft, Osnexus 3 Linux Kernel, Windows, Quantastor 2024-11-21 N/A 8.7 HIGH
An authenticated attacker is able to create alerts that trigger a stored XSS attack.
CVE-2021-42056 3 Linux, Microsoft, Thalesgroup 3 Linux Kernel, Windows, Safenet Authentication Client 2024-11-21 7.2 HIGH 6.7 MEDIUM
Thales Safenet Authentication Client (SAC) for Linux and Windows through 10.7.7 creates insecure temporary hid and lock files allowing a local attacker, through a symlink attack, to overwrite arbitrary files, and potentially achieve arbitrary command execution with high privileges.
CVE-2021-42008 3 Debian, Linux, Netapp 20 Debian Linux, Linux Kernel, H300e and 17 more 2024-11-21 6.9 MEDIUM 7.8 HIGH
The decode_data function in drivers/net/hamradio/6pack.c in the Linux kernel before 5.13.13 has a slab out-of-bounds write. Input from a process that has the CAP_NET_ADMIN capability can lead to root access.
CVE-2021-41864 4 Debian, Fedoraproject, Linux and 1 more 24 Debian Linux, Fedora, Linux Kernel and 21 more 2024-11-21 4.6 MEDIUM 7.8 HIGH
prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel before 5.14.12 allows unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds write.
CVE-2021-41073 4 Debian, Fedoraproject, Linux and 1 more 21 Debian Linux, Fedora, Linux Kernel and 18 more 2024-11-21 7.2 HIGH 7.8 HIGH
loop_rw_iter in fs/io_uring.c in the Linux kernel 5.10 through 5.14.6 allows local users to gain privileges by using IORING_OP_PROVIDE_BUFFERS to trigger a free of a kernel buffer, as demonstrated by using /proc/<pid>/maps for exploitation.
CVE-2021-40830 3 Amazon, Linux, Opengroup 4 Amazon Web Services Aws-c-io, Amazon Web Services Internet Of Things Device Software Development Kit V2, Linux Kernel and 1 more 2024-11-21 5.8 MEDIUM 6.3 MEDIUM
The AWS IoT Device SDK v2 for Java, Python, C++ and Node.js appends a user supplied Certificate Authority (CA) to the root CAs instead of overriding it on Unix systems. TLS handshakes will thus succeed if the peer can be verified either from the user-supplied CA or the system’s default trust-store. Attackers with access to a host’s trust stores or are able to compromise a certificate authority already in the host's trust store (note: the attacker must also be able to spoof DNS in this case) may be able to use this issue to bypass CA pinning. An attacker could then spoof the MQTT broker, and either drop traffic and/or respond with the attacker's data, but they would not be able to forward this data on to the MQTT broker because the attacker would still need the user's private keys to authenticate against the MQTT broker. The 'aws_tls_ctx_options_override_default_trust_store_*' function within the aws-c-io submodule has been updated to override the default trust store. This corrects this issue. This issue affects: Amazon Web Services AWS IoT Device SDK v2 for Java versions prior to 1.5.0 on Linux/Unix. Amazon Web Services AWS IoT Device SDK v2 for Python versions prior to 1.6.1 on Linux/Unix. Amazon Web Services AWS IoT Device SDK v2 for C++ versions prior to 1.12.7 on Linux/Unix. Amazon Web Services AWS IoT Device SDK v2 for Node.js versions prior to 1.5.3 on Linux/Unix. Amazon Web Services AWS-C-IO 0.10.4 on Linux/Unix.
CVE-2021-40745 3 Adobe, Linux, Microsoft 3 Campaign, Linux Kernel, Windows 2024-11-21 5.0 MEDIUM 7.5 HIGH
Adobe Campaign version 21.2.1 (and earlier) is affected by a Path Traversal vulnerability that could lead to reading arbitrary server files. By leveraging an exposed XML file, an unauthenticated attacker can enumerate other files on the server.
CVE-2021-40490 4 Debian, Fedoraproject, Linux and 1 more 29 Debian Linux, Fedora, Linux Kernel and 26 more 2024-11-21 4.4 MEDIUM 7.0 HIGH
A race condition was discovered in ext4_write_inline_data_end in fs/ext4/inline.c in the ext4 subsystem in the Linux kernel through 5.13.13.
CVE-2021-3923 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2024-11-21 N/A 2.3 LOW
A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a privileged local account can leak kernel stack information when issuing commands to the /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it can be further used to defeat existing kernel protection mechanisms.
CVE-2021-3864 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2024-11-21 N/A 7.0 HIGH
A flaw was found in the way the dumpable flag setting was handled when certain SUID binaries executed its descendants. The prerequisite is a SUID binary that sets real UID equal to effective UID, and real GID equal to effective GID. The descendant will then have a dumpable value set to 1. As a result, if the descendant process crashes and core_pattern is set to a relative value, its core dump is stored in the current directory with uid:gid permissions. An unprivileged local user with eligible root SUID binary could use this flaw to place core dumps into root-owned directories, potentially resulting in escalation of privileges.
CVE-2021-3847 2 Fedoraproject, Linux 2 Fedora, Linux Kernel 2024-11-21 7.2 HIGH 7.8 HIGH
An unauthorized access to the execution of the setuid file with capabilities flaw in the Linux kernel OverlayFS subsystem was found in the way user copying a capable file from a nosuid mount into another mount. A local user could use this flaw to escalate their privileges on the system.
CVE-2021-3773 4 Fedoraproject, Linux, Oracle and 1 more 6 Fedora, Linux Kernel, Communications Cloud Native Core Binding Support Function and 3 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
A flaw in netfilter could allow a network-connected attacker to infer openvpn connection endpoint information for further use in traditional network attacks.
CVE-2021-3772 5 Debian, Linux, Netapp and 2 more 26 Debian Linux, Linux Kernel, E-series Santricity Os Controller and 23 more 2024-11-21 5.8 MEDIUM 6.5 MEDIUM
A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and the attacker can send packets with spoofed IP addresses.
CVE-2021-3764 1 Linux 1 Linux Kernel 2024-11-21 N/A 5.5 MEDIUM
A memory leak flaw was found in the Linux kernel's ccp_run_aes_gcm_cmd() function that allows an attacker to cause a denial of service. The vulnerability is similar to the older CVE-2019-18808. The highest threat from this vulnerability is to system availability.
CVE-2021-3760 4 Debian, Fedoraproject, Linux and 1 more 19 Debian Linux, Fedora, Linux Kernel and 16 more 2024-11-21 7.2 HIGH 7.8 HIGH
