Date Id Summary Products Score Patch Annotated
2021-07-22 CVE-2021-29657 arch/x86/kvm/svm/nested.c in the Linux kernel before 5.11.12 has a use-after-free in which an AMD KVM guest can bypass access control on host OS MSRs when there are nested guests, aka CID-a58d9166a756. This occurs because of a TOCTOU race condition associated with a VMCB12 double fetch in nested_svm_vmrun. Linux_kernel 7.4
2021-07-26 CVE-2021-37576 arch/powerpc/kvm/book3s_rtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest OS users to cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e. Fedora, Linux_kernel 7.8
2021-08-02 CVE-2021-35477 In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store operation does not necessarily occur before a store operation that has an attacker-controlled value. Debian_linux, Fedora, Linux_kernel 5.5
2021-08-02 CVE-2021-34556 In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects the possibility of uninitialized memory locations on the BPF stack. Debian_linux, Fedora, Linux_kernel 5.5
2021-08-05 CVE-2021-3679 A lack of CPU resource in the Linux kernel tracing module functionality in versions prior to 5.14-rc3 was found in the way user uses trace ring buffer in a specific way. Only privileged local users (with CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service. Debian_linux, Linux_kernel, Enterprise_linux 5.5
2021-08-05 CVE-2021-3655 A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on inbound SCTP packets may allow the kernel to read uninitialized memory. Debian_linux, Linux_kernel, Enterprise_linux 3.3
2021-08-07 CVE-2021-38166 In kernel/bpf/hashtab.c in the Linux kernel through 5.13.8, there is an integer overflow and out-of-bounds write when many elements are placed in a single bucket. NOTE: exploitation might be impractical without the CAP_SYS_ADMIN capability. Debian_linux, Fedora, Linux_kernel 7.8
2021-08-08 CVE-2021-38198 arch/x86/kvm/mmu/paging_tmpl.h in the Linux kernel before 5.12.11 incorrectly computes the access permissions of a shadow page, leading to a missing guest protection page fault. Debian_linux, Linux_kernel 5.5
2021-08-08 CVE-2021-38199 fs/nfs/nfs4client.c in the Linux kernel before 5.13.4 has incorrect connection-setup ordering, which allows operators of remote NFSv4 servers to cause a denial of service (hanging of mounts) by arranging for those servers to be unreachable during trunking detection. Debian_linux, Linux_kernel, Element_software, Hci_bootstrap_os, Hci_management_node, Solidfire 6.5
2021-08-08 CVE-2021-38200 arch/powerpc/perf/core-book3s.c in the Linux kernel before 5.12.13, on systems with perf_event_paranoid=-1 and no specific PMU driver support registered, allows local users to cause a denial of service (perf_instruction_pointer NULL pointer dereference and OOPS) via a "perf record" command.
