CVE-2021-3941 4 Debian, Fedoraproject, Openexr and 1 more 4 Debian Linux, Fedora, Openexr and 1 more 2024-11-21 6.5 Medium
In ImfChromaticities.cpp routine RGBtoXYZ(), there are some division operations such as `float Z = (1 - chroma.white.x - chroma.white.y) * Y / chroma.white.y;` and `chroma.green.y * (X + Z))) / d;` but the divisor is not checked for a 0 value. A specially crafted file could trigger a divide-by-zero condition which could affect the availability of programs linked with OpenEXR.
CVE-2021-3905 4 Canonical, Fedoraproject, Openvswitch and 1 more 5 Ubuntu Linux, Fedora, Openvswitch and 2 more 2024-11-21 7.5 High
A memory leak was found in Open vSwitch (OVS) during userspace IP fragmentation processing. An attacker could use this flaw to potentially exhaust available memory by keeping sending packet fragments.

CVE-2021-3839 3 Dpdk, Fedoraproject, Redhat 4 Data Plane Development Kit, Fedora, Enterprise Linux and 1 more 2024-11-21 7.5 High
A flaw was found in the vhost library in DPDK. Function vhost_user_set_inflight_fd() does not validate `msg->payload.inflight.num_queues`, possibly causing out-of-bounds memory read/write. Any software using DPDK vhost library may crash as a result of this vulnerability.
CVE-2021-3826 3 Fedoraproject, Gnu, Redhat 4 Fedora, Gcc, Enterprise Linux and 1 more 2024-11-21 6.5 Medium
Heap/stack buffer overflow in the dlang_lname function in d-demangle.c in libiberty allows attackers to potentially cause a denial of service (segmentation fault and crash) via a crafted mangled symbol.
CVE-2021-3802 3 Fedoraproject, Redhat, Udisks Project 3 Fedora, Enterprise Linux, Udisks 2024-11-21 4.2 Medium
A vulnerability found in udisks2. This flaw allows an attacker to input a specially crafted image file/USB leading to kernel panic. The highest threat from this vulnerability is to system availability.

CVE-2021-3752 6 Debian, Fedoraproject, Linux and 3 more 28 Debian Linux, Fedora, Linux Kernel and 25 more 2024-11-21 7.1 High
A use-after-free flaw was found in the Linux kernel’s Bluetooth subsystem in the way user calls connect to the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the system or escalate their privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2021-3748 5 Canonical, Debian, Fedoraproject and 2 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2024-11-21 7.5 High
A use-after-free vulnerability was found in the virtio-net device of QEMU. It could occur when the descriptor's address belongs to the non direct access region, due to num_buffers being set after the virtqueue elem has been unmapped. A malicious guest could use this flaw to crash QEMU, resulting in a denial of service condition, or potentially execute code on the host with the privileges of the QEMU process.
CVE-2021-3746 3 Fedoraproject, Libtpms Project, Redhat 3 Fedora, Libtpms, Enterprise Linux 2024-11-21 6.5 Medium
A flaw was found in the libtpms code that may cause access beyond the boundary of internal buffers. The vulnerability is triggered by specially-crafted TPM2 command packets that then trigger the issue when the state of the TPM2's volatile state is written. The highest threat from this vulnerability is to system availability. This issue affects libtpms versions before 0.8.5, before 0.7.9 and before 0.6.6.
CVE-2021-3744 5 Debian, Fedoraproject, Linux and 2 more 24 Debian Linux, Fedora, Linux Kernel and 21 more 2024-11-21 5.5 Medium
A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption). This vulnerability is similar with the older CVE-2019-18808.
CVE-2021-3743 5 Fedoraproject, Linux, Netapp and 2 more 22 Fedora, Linux Kernel, H300e and 19 more 2024-11-21 7.1 High
An out-of-bounds (OOB) memory read flaw was found in the Qualcomm IPC router protocol in the Linux kernel. A missing sanity check allows a local attacker to gain access to out-of-bounds memory, leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability.
CVE-2021-3700 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2024-11-21 6.4 Medium
A use-after-free vulnerability was found in usbredir in versions prior to 0.11.0 in the usbredirparser_serialize() in usbredirparser/usbredirparser.c. This issue occurs when serializing large amounts of buffered write data in the case of a slow or blocked destination.
CVE-2021-3695 4 Fedoraproject, Gnu, Netapp and 1 more 16 Fedora, Grub2, Ontap Select Deploy Administration Utility and 13 more 2024-11-21 4.5 Medium
A crafted 16-bit grayscale PNG image may lead to a out-of-bounds write in the heap area. An attacker may take advantage of that to cause heap data corruption or eventually arbitrary code execution and circumvent secure boot protections. This issue has a high complexity to be exploited as an attacker needs to perform some triage over the heap layout to achieve signifcant results, also the values written into the memory are repeated three times in a row making difficult to produce valid payloads. This flaw affects grub2 versions prior grub-2.12.
CVE-2021-3677 3 Fedoraproject, Postgresql, Redhat 9 Fedora, Postgresql, Enterprise Linux and 6 more 2024-11-21 6.5 Medium
A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects. If server settings include max_worker_processes=0, the known versions of this attack are infeasible. However, undiscovered variants of the attack may be independent of that setting.
CVE-2021-3672 6 C-ares Project, Fedoraproject, Nodejs and 3 more 19 C-ares, Fedora, Node.js and 16 more 2024-11-21 5.6 Medium
A flaw was found in c-ares library, where a missing input validation check of host names returned by DNS (Domain Name Servers) can lead to output of wrong hostnames which might potentially lead to Domain Hijacking. The highest threat from this vulnerability is to confidentiality and integrity as well as system availability.
CVE-2021-3659 3 Fedoraproject, Linux, Redhat 17 Fedora, Linux Kernel, Codeready Linux Builder and 14 more 2024-11-21 5.5 Medium
A NULL pointer dereference flaw was found in the Linux kernel’s IEEE 802.15.4 wireless networking subsystem in the way the user closes the LR-WPAN connection. This flaw allows a local user to crash the system. The highest threat from this vulnerability is to system availability.
CVE-2021-3657 4 Debian, Fedoraproject, Isync Project and 1 more 4 Debian Linux, Fedora, Isync and 1 more 2024-11-21 9.8 Critical
A flaw was found in mbsync versions prior to 1.4.4. Due to inadequate handling of extremely large (>=2GiB) IMAP literals, malicious or compromised IMAP servers, and hypothetically even external email senders, could cause several different buffer overflows, which could conceivably be exploited for remote code execution.
CVE-2021-3656 3 Fedoraproject, Linux, Redhat 31 Fedora, Linux Kernel, 3scale Api Management and 28 more 2024-11-21 8.8 High
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virt_ext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape.
