|---|---|---|---|---|---|
| CVE-2021-4197 | 5 Broadcom, Debian, Linux and 2 more | 14 Brocade Fabric Operating System Firmware, Debian Linux, Linux Kernel and 11 more | 2023-11-07 | 7.2 HIGH | 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-2021-4157 | 4 Fedoraproject, Linux, Netapp and 1 more | 17 Fedora, Linux Kernel, H300e and 14 more | 2023-11-07 | 7.4 HIGH | 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-2021-4095 | 2 Fedoraproject, Linux | 2 Fedora, Linux Kernel | 2023-11-07 | 1.9 LOW | 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 | 2023-11-07 | 7.2 HIGH | 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-2021-4090 | 2 Linux, Netapp | 17 Linux Kernel, H300e, H300e Firmware and 14 more | 2023-11-07 | 6.6 MEDIUM | 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. | |||||

| 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 | 2 Fedoraproject, Linux | 2 Fedora, Linux Kernel | 2023-11-07 | 4.9 MEDIUM | 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-2021-41864 | 4 Debian, Fedoraproject, Linux and 1 more | 24 Debian Linux, Fedora, Linux Kernel and 21 more | 2023-11-07 | 4.6 MEDIUM | 7.8 HIGH |

| 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. | |||||
