CVE-2021-4002 5 Debian, Fedoraproject, Linux and 2 more 7 Debian Linux, Fedora, Linux Kernel and 4 more 2024-08-03 4.4 Medium
A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the memory pages. A local user could use this flaw to get unauthorized access to some data.
CVE-2021-4023 2 Fedoraproject, Linux 2 Fedora, Linux Kernel 2024-08-03 5.5 Medium
A flaw was found in the io-workqueue implementation in the Linux kernel versions prior to 5.15-rc1. The kernel can panic when an improper cancellation operation triggers the submission of new io-uring operations during a shortage of free space. This flaw allows a local user with permissions to execute io-uring requests to possibly crash the system.
CVE-2021-4010 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2024-08-03 7.8 High
A flaw was found in xorg-x11-server in versions before 21.1.2 and before 1.20.14. An out-of-bounds access can occur in the SProcScreenSaverSuspend function. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2021-3997 3 Fedoraproject, Redhat, Systemd Project 3 Fedora, Enterprise Linux, Systemd 2024-08-03 5.5 Medium
A flaw was found in systemd. An uncontrolled recursion in systemd-tmpfiles may lead to a denial of service at boot time when too many nested directories are created in /tmp.
CVE-2021-3178 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-08-03 6.5 Medium
fs/nfsd/nfs3xdr.c in the Linux kernel through 5.10.8, when there is an NFS export of a subdirectory of a filesystem, allows remote attackers to traverse to other parts of the filesystem via READDIRPLUS. NOTE: some parties argue that such a subdirectory export is not intended to prevent this attack; see also the exports(5) no_subtree_check default behavior
CVE-2021-3974 3 Debian, Fedoraproject, Vim 3 Debian Linux, Fedora, Vim 2024-08-03 7.8 High
vim is vulnerable to Use After Free
CVE-2021-3979 2 Fedoraproject, Redhat 8 Fedora, Ceph Storage, Ceph Storage For Ibm Z Systems and 5 more 2024-08-03 6.5 Medium
A key length flaw was found in Red Hat Ceph Storage. An attacker can exploit the fact that the key length is incorrectly passed in an encryption algorithm to create a non random key, which is weaker and can be exploited for loss of confidentiality and integrity on encrypted disks.
CVE-2021-3981 3 Fedoraproject, Gnu, Redhat 3 Fedora, Grub2, Enterprise Linux 2024-08-03 3.3 Low
A flaw in grub2 was found where its configuration file, known as grub.cfg, is being created with the wrong permission set allowing non privileged users to read its content. This represents a low severity confidentiality issue, as those users can eventually read any encrypted passwords present in grub.cfg. This flaw affects grub2 2.06 and previous versions. This issue has been fixed in grub upstream but no version with the fix is currently released.
CVE-2021-3975 5 Canonical, Debian, Fedoraproject and 2 more 15 Ubuntu Linux, Debian Linux, Fedora and 12 more 2024-08-03 6.5 Medium
A use-after-free flaw was found in libvirt. The qemuMonitorUnregister() function in qemuProcessHandleMonitorEOF is called using multiple threads without being adequately protected by a monitor lock. This flaw could be triggered by the virConnectGetAllDomainStats API when the guest is shutting down. An unprivileged client with a read-only connection could use this flaw to perform a denial of service attack by causing the libvirt daemon to crash.
CVE-2021-3968 2 Fedoraproject, Vim 2 Fedora, Vim 2024-08-03 8.0 High
vim is vulnerable to Heap-based Buffer Overflow
CVE-2021-3935 4 Debian, Fedoraproject, Pgbouncer and 1 more 4 Debian Linux, Fedora, Pgbouncer and 1 more 2024-08-03 8.1 High
When PgBouncer is configured to use "cert" authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of TLS certificate verification and encryption. This flaw affects PgBouncer versions prior to 1.16.1.
CVE-2021-3984 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2024-08-03 7.8 High
vim is vulnerable to Heap-based Buffer Overflow
CVE-2021-3923 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2024-08-03 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-2021-3928 3 Debian, Fedoraproject, Vim 3 Debian Linux, Fedora, Vim 2024-08-03 7.8 High
vim is vulnerable to Use of Uninitialized Variable
CVE-2021-3927 3 Debian, Fedoraproject, Vim 3 Debian Linux, Fedora, Vim 2024-08-03 7.8 High
vim is vulnerable to Heap-based Buffer Overflow
CVE-2021-3973 3 Debian, Fedoraproject, Vim 3 Debian Linux, Fedora, Vim 2024-08-03 7.8 High
vim is vulnerable to Heap-based Buffer Overflow
CVE-2021-3941 4 Debian, Fedoraproject, Openexr and 1 more 4 Debian Linux, Fedora, Openexr and 1 more 2024-08-03 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-2021-3839 3 Dpdk, Fedoraproject, Redhat 4 Data Plane Development Kit, Fedora, Enterprise Linux and 1 more 2024-08-03 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-2021-3929 2 Fedoraproject, Qemu 2 Fedora, Qemu 2024-08-03 8.2 High
A DMA reentrancy issue was found in the NVM Express Controller (NVME) emulation in QEMU. This CVE is similar to CVE-2021-3750 and, just like it, when the reentrancy write triggers the reset function nvme_ctrl_reset(), data structs will be freed leading to a use-after-free issue. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition or, potentially, executing arbitrary code within the context of the QEMU process on the host.
CVE-2021-3903 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2024-08-03 7.8 High
