CVE-2021-4037 3 Debian, Linux, Redhat 4 Debian Linux, Linux Kernel, Enterprise Linux and 1 more 2024-11-21 7.8 High
A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that allows local users to create files for the XFS file-system with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not. This vulnerability is similar to the previous CVE-2018-13405 and adds the missed fix for the XFS.
CVE-2021-4028 3 Linux, Redhat, Suse 9 Linux Kernel, Enterprise Linux, Rhel Aus and 6 more 2024-11-21 7.8 High
A flaw in the Linux kernel's implementation of RDMA communications manager listener code allowed an attacker with local access to setup a socket to listen on a high port allowing for a list element to be used after free. Given the ability to execute code, a local attacker could leverage this use-after-free to crash the system or possibly escalate privileges on the system.
CVE-2021-4002 5 Debian, Fedoraproject, Linux and 2 more 7 Debian Linux, Fedora, Linux Kernel and 4 more 2024-11-21 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-2021-45486 3 Linux, Oracle, Redhat 6 Linux Kernel, Communications Cloud Native Core Binding Support Function, Communications Cloud Native Core Network Exposure Function and 3 more 2024-11-21 3.5 Low
In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak because the hash table is very small.
CVE-2021-45485 4 Linux, Netapp, Oracle and 1 more 46 Linux Kernel, Aff A400, Aff A400 Firmware and 43 more 2024-11-21 7.5 High
In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses.
CVE-2021-44733 5 Debian, Fedoraproject, Linux and 2 more 20 Debian Linux, Fedora, Linux Kernel and 17 more 2024-11-21 7.0 High
A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11. This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory object.
CVE-2021-43976 6 Debian, Fedoraproject, Linux and 3 more 24 Debian Linux, Fedora, Linux Kernel and 21 more 2024-11-21 4.6 Medium

In the Linux kernel through 5.15.2, hw_atl_utils_fw_rpc_wait in drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allows an attacker (who can introduce a crafted device) to trigger an out-of-bounds write via a crafted length value.
CVE-2021-43389 4 Debian, Linux, Oracle and 1 more 6 Debian Linux, Linux Kernel, Communications Cloud Native Core Binding Support Function and 3 more 2024-11-21 5.5 Medium
An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in the detach_capi_ctr function in drivers/isdn/capi/kcapi.c.
CVE-2021-43267 4 Fedoraproject, Linux, Netapp and 1 more 19 Fedora, Linux Kernel, H300e and 16 more 2024-11-21 9.8 Critical
An issue was discovered in net/tipc/crypto.c in the Linux kernel before 5.14.16. The Transparent Inter-Process Communication (TIPC) functionality allows remote attackers to exploit insufficient validation of user-supplied sizes for the MSG_CRYPTO message type.
CVE-2021-43056 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2024-11-21 5.5 Medium
An issue was discovered in the Linux kernel for powerpc before 5.14.15. It allows a malicious KVM guest to crash the host, when the host is running on Power8, due to an arch/powerpc/kvm/book3s_hv_rmhandlers.S implementation bug in the handling of the SRR1 register values.
CVE-2021-42739 6 Debian, Fedoraproject, Linux and 3 more 10 Debian Linux, Fedora, Linux Kernel and 7 more 2024-11-21 6.7 Medium
The firewire subsystem in the Linux kernel through 5.14.13 has a buffer overflow related to drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandles bounds checking.
CVE-2021-41864 5 Debian, Fedoraproject, Linux and 2 more 25 Debian Linux, Fedora, Linux Kernel and 22 more 2024-11-21 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-2021-41817 6 Debian, Fedoraproject, Opensuse and 3 more 12 Debian Linux, Fedora, Factory and 9 more 2024-11-21 7.5 High
Date.parse in the date gem through 3.2.0 for Ruby allows ReDoS (regular expression Denial of Service) via a long string. The fixed versions are 3.2.1, 3.1.2, 3.0.2, and 2.0.1.

CVE-2021-3864 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2024-11-21 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-2021-3772 5 Debian, Linux, Netapp and 2 more 26 Debian Linux, Linux Kernel, E-series Santricity Os Controller and 23 more 2024-11-21 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 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2024-11-21 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-2021-3759 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2024-11-21 5.5 Medium
A memory overflow vulnerability was found in the Linux kernel’s ipc functionality of the memcg subsystem, in the way a user calls the semget function multiple times, creating semaphores. This flaw allows a local user to starve the resources, causing a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2021-3753 3 Linux, Netapp, Redhat 18 Linux Kernel, Active Iq Unified Manager, Bootstrap Os and 15 more 2024-11-21 4.7 Medium
A race problem was seen in the vt_k_ioctl in drivers/tty/vt/vt_ioctl.c in the Linux kernel, which may cause an out of bounds read in vt as the write access to vc_mode is not protected by lock-in vt_ioctl (KDSETMDE). The highest threat from this vulnerability is to data confidentiality.
