| CVE-2021-4218 | 1 Linux | 1 Linux Kernel | 2024-08-03 | 5.5 Medium |
| A flaw was found in the Linux kernel’s implementation of reading the SVC RDMA counters. Reading the counter sysctl panics the system. This flaw allows a local attacker with local access to cause a denial of service while the system reboots. The issue is specific to CentOS/RHEL. | ||||
| CVE-2021-4157 | 5 Fedoraproject, Linux, Netapp and 2 more | 18 Fedora, Linux Kernel, H300e and 15 more | 2024-08-03 | 8.0 High |
| An out of memory bounds write flaw (1 or 2 bytes of memory) in the Linux kernel NFS subsystem was found in the way users use mirroring (replication of files with NFS). A user, having access to the NFS mount, could potentially use this flaw to crash the system or escalate privileges on the system. | ||||
| CVE-2021-4150 | 1 Linux | 1 Linux Kernel | 2024-08-03 | 5.5 Medium |
| A use-after-free flaw was found in the add_partition in block/partitions/core.c in the Linux kernel. A local attacker with user privileges could cause a denial of service on the system. The issue results from the lack of code cleanup when device_add call fails when adding a partition to the disk. | ||||
| CVE-2021-4203 | 4 Linux, Netapp, Oracle and 1 more | 25 Linux Kernel, A700s, A700s Firmware and 22 more | 2024-08-03 | 6.8 Medium |
| A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a user privileges may crash the system or leak internal kernel information. | ||||
| CVE-2021-4149 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2024-08-03 | 5.5 Medium |
| A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of service (DOS) due to a deadlock problem. | ||||
| CVE-2021-4155 | 2 Linux, Redhat | 9 Linux Kernel, Enterprise Linux, Rhel Aus and 6 more | 2024-08-03 | 5.5 Medium |
| A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS filesystem otherwise not accessible to them. | ||||
| CVE-2021-4197 | 6 Broadcom, Debian, Linux and 3 more | 16 Brocade Fabric Operating System Firmware, Debian Linux, Linux Kernel and 13 more | 2024-08-03 | 7.8 High |
| An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system. | ||||
| CVE-2021-4028 | 3 Linux, Redhat, Suse | 9 Linux Kernel, Enterprise Linux, Rhel Aus and 6 more | 2024-08-03 | 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-2021-4159 | 3 Debian, Linux, Redhat | 3 Debian Linux, Linux Kernel, Enterprise Linux | 2024-08-03 | 4.4 Medium |
| A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures. Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel. | ||||
| CVE-2021-4202 | 1 Linux | 1 Linux Kernel | 2024-08-03 | 7.0 High |
| A use-after-free flaw was found in nci_request in net/nfc/nci/core.c in NFC Controller Interface (NCI) in the Linux kernel. This flaw could allow a local attacker with user privileges to cause a data race problem while the device is getting removed, leading to a privilege escalation problem. | ||||
| CVE-2021-4135 | 1 Linux | 1 Linux Kernel | 2024-08-03 | 5.5 Medium |
| A memory leak vulnerability was found in the Linux kernel's eBPF for the Simulated networking device driver in the way user uses BPF for the device such that function nsim_map_alloc_elem being called. A local user could use this flaw to get unauthorized access to some data. | ||||
| CVE-2021-4148 | 2 Fedoraproject, Linux | 2 Fedora, Linux Kernel | 2024-08-03 | 5.5 Medium |
| A vulnerability was found in the Linux kernel's block_invalidatepage in fs/buffer.c in the filesystem. A missing sanity check may allow a local attacker with user privilege to cause a denial of service (DOS) problem. | ||||
| CVE-2021-4083 | 5 Debian, Linux, Netapp and 2 more | 30 Debian Linux, Linux Kernel, H300e and 27 more | 2024-08-03 | 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-2021-4090 | 2 Linux, Netapp | 17 Linux Kernel, H300e, H300e Firmware and 14 more | 2024-08-03 | 7.1 High |
| An out-of-bounds (OOB) memory write flaw was found in the NFSD in the Linux kernel. Missing sanity may lead to a write beyond bmval[bmlen-1] in nfsd4_decode_bitmap4 in fs/nfsd/nfs4xdr.c. In this flaw, a local attacker with user privilege may gain access to out-of-bounds memory, leading to a system integrity and confidentiality threat. | ||||
| CVE-2021-4001 | 1 Linux | 1 Linux Kernel | 2024-08-03 | 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-2021-4095 | 2 Fedoraproject, Linux | 2 Fedora, Linux Kernel | 2024-08-03 | 5.5 Medium |
| A NULL pointer dereference was found in the Linux kernel's KVM when dirty ring logging is enabled without an active vCPU context. An unprivileged local attacker on the host may use this flaw to cause a kernel oops condition and thus a denial of service by issuing a KVM_XEN_HVM_SET_ATTR ioctl. This flaw affects Linux kernel versions prior to 5.17-rc1. | ||||
| CVE-2021-4093 | 4 Canonical, Fedoraproject, Linux and 1 more | 4 Ubuntu Linux, Fedora, Linux Kernel and 1 more | 2024-08-03 | 8.8 High |
| A flaw was found in the KVM's AMD code for supporting the Secure Encrypted Virtualization-Encrypted State (SEV-ES). A KVM guest using SEV-ES can trigger out-of-bounds reads and writes in the host kernel via a malicious VMGEXIT for a string I/O instruction (for example, outs or ins) using the exit reason SVM_EXIT_IOIO. This issue results in a crash of the entire system or a potential guest-to-host escape scenario. | ||||
| 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-2021-4032 | 1 Linux | 1 Linux Kernel | 2024-08-03 | 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. | ||||
