| CVE | Vendors | Products | Updated | CVSS v3.1 |
|---|---|---|---|---|
| CVE-2021-4083 | 5 Debian, Linux, Netapp and 2 more | 30 Debian Linux, Linux Kernel, H300e and 27 more | 2024-11-21 | 7.0 High |
| A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on the system. This flaw affects Linux kernel versions prior to 5.16-rc4. | ||||
| 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-2021-4032 | 1 Linux | 1 Linux Kernel | 2024-11-21 | 4.4 Medium |
| A vulnerability was found in the Linux kernel's KVM subsystem in arch/x86/kvm/lapic.c kvm_free_lapic when a failure allocation was detected. In this flaw the KVM subsystem may crash the kernel due to mishandling of memory errors that happens during VCPU construction, which allows an attacker with special user privilege to cause a denial of service. This flaw affects kernel versions prior to 5.15 rc7. | ||||
| 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-2021-4023 | 2 Fedoraproject, Linux | 2 Fedora, Linux Kernel | 2024-11-21 | 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-2021-4002 | 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-2021-4001 | 1 Linux | 1 Linux Kernel | 2024-11-21 | 4.1 Medium |
| A race condition was found in the Linux kernel's ebpf verifier between bpf_map_update_elem and bpf_map_freeze due to a missing lock in kernel/bpf/syscall.c. In this flaw, a local user with a special privilege (cap_sys_admin or cap_bpf) can modify the frozen mapped address space. This flaw affects kernel versions prior to 5.16 rc2. | ||||
| CVE-2021-46283 | 1 Linux | 1 Linux Kernel | 2024-11-21 | 5.5 Medium |
| nf_tables_newset in net/netfilter/nf_tables_api.c in the Linux kernel before 5.12.13 allows local users to cause a denial of service (NULL pointer dereference and general protection fault) because of the missing initialization for nft_set_elem_expr_alloc. A local user can set a netfilter table expression in their own namespace. | ||||
| CVE-2021-45884 | 4 Apple, Brave, Linux and 1 more | 4 Macos, Brave, Linux Kernel and 1 more | 2024-11-21 | 7.5 High |
| In Brave Desktop 1.17 through 1.33 before 1.33.106, when CNAME-based adblocking and a proxying extension with a SOCKS fallback are enabled, additional DNS requests are issued outside of the proxying extension using the system's DNS settings, resulting in information disclosure. NOTE: this issue exists because of an incomplete fix for CVE-2021-21323 and CVE-2021-22916. | ||||
| CVE-2021-45868 | 2 Linux, Netapp | 17 Linux Kernel, H300e, H300e Firmware and 14 more | 2024-11-21 | 5.5 Medium |
| In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a corrupted quota file. | ||||
| 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-2021-45480 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2024-11-21 | 5.5 Medium |
| An issue was discovered in the Linux kernel before 5.15.11. There is a memory leak in the __rds_conn_create() function in net/rds/connection.c in a certain combination of circumstances. | ||||
| CVE-2021-45469 | 4 Debian, Fedoraproject, Linux and 1 more | 19 Debian Linux, Fedora, Linux Kernel and 16 more | 2024-11-21 | 7.8 High |
| In __f2fs_setxattr in fs/f2fs/xattr.c in the Linux kernel through 5.15.11, there is an out-of-bounds memory access when an inode has an invalid last xattr entry. | ||||
| CVE-2021-45402 | 1 Linux | 1 Linux Kernel | 2024-11-21 | 5.5 Medium |
| The check_alu_op() function in kernel/bpf/verifier.c in the Linux kernel through v5.16-rc5 did not properly update bounds while handling the mov32 instruction, which allows local users to obtain potentially sensitive address information, aka a "pointer leak." | ||||
| CVE-2021-45100 | 3 Ksmbd Project, Linux, Netapp | 18 Ksmbd, Linux Kernel, H300e and 15 more | 2024-11-21 | 7.5 High |
| The ksmbd server through 3.4.2, as used in the Linux kernel through 5.15.8, sometimes communicates in cleartext even though encryption has been enabled. This occurs because it sets the SMB2_GLOBAL_CAP_ENCRYPTION flag when using the SMB 3.1.1 protocol, which is a violation of the SMB protocol specification. When Windows 10 detects this protocol violation, it disables encryption. | ||||
| CVE-2021-45095 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2024-11-21 | 5.5 Medium |
| pep_sock_accept in net/phonet/pep.c in the Linux kernel through 5.15.8 has a refcount leak. | ||||
| CVE-2021-44879 | 1 Linux | 1 Linux Kernel | 2024-11-21 | 5.5 Medium |
| In gc_data_segment in fs/f2fs/gc.c in the Linux kernel before 5.16.3, special files are not considered, leading to a move_data_page NULL pointer dereference. | ||||
| 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-2021-44458 | 2 Linux, Mirantis | 2 Linux Kernel, Lens | 2024-11-21 | 8.3 High |
| Linux users running Lens 5.2.6 and earlier could be compromised by visiting a malicious website. The malicious website could make websocket connections from the victim's browser to Lens and so operate the local terminal feature. This would allow the attacker to execute arbitrary commands as the Lens user. | ||||
