#Vulnerabilities 4822
Date Id Summary Products Score Patch Annotated
2021-05-28 CVE-2021-20239 A flaw was found in the Linux kernel in versions before 5.4.92 in the BPF protocol. This flaw allows an attacker with a local account to leak information about kernel internal addresses. The highest threat from this vulnerability is to confidentiality. Fedora, Linux_kernel, Enterprise_linux 3.3
2021-07-09 CVE-2021-3612 An out-of-bounds memory write flaw was found in the Linux kernel's joystick devices subsystem in versions before 5.9-rc1, in the way the user calls ioctl JSIOCSBTNMAP. This flaw allows a local user to crash the system or possibly escalate their privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Debian_linux, Fedora, Linux_kernel, Cloud_backup, H300e_firmware, H300s_firmware, H410c_firmware, H410s_firmware, H500e_firmware, H500s_firmware, H700e_firmware, H700s_firmware, Solidfire_baseboard_management_controller_firmware, Communications_cloud_native_core_binding_support_function, Communications_cloud_native_core_network_exposure_function, Communications_cloud_native_core_policy, Enterprise_linux 7.8
2021-07-20 CVE-2021-33909 fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an unprivileged user, aka CID-8cae8cd89f05. Debian_linux, Fedora, Linux_kernel, Hci_management_node, Solidfire, Communications_session_border_controller, Sma1000_firmware 7.8
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
2021-08-07 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
2021-08-13 CVE-2021-3573 A use-after-free in function hci_sock_bound_ioctl() of the Linux kernel HCI subsystem was found in the way user calls ioct HCIUNBLOCKADDR or other way triggers race condition of the call hci_unregister_dev() together with one of the calls hci_sock_blacklist_add(), hci_sock_blacklist_del(), hci_get_conn_info(), hci_get_auth_info(). A privileged local user could use this flaw to crash the system or escalate their privileges on the system. This flaw affects the Linux kernel versions prior to 5.13-rc5. Fedora, Linux_kernel, Enterprise_linux 6.4
2021-09-03 CVE-2021-40490 A race condition was discovered in ext4_write_inline_data_end in fs/ext4/inline.c in the ext4 subsystem in the Linux kernel through 5.13.13. Debian_linux, Fedora, Linux_kernel, Aff_a250_firmware, Fas_500f_firmware, H300e_firmware, H300s_firmware, H410c_firmware, H410s_firmware, H500e_firmware, H500s_firmware, H610c_firmware, H610s_firmware, H615c_firmware, H700e_firmware, H700s_firmware 7.0
2021-09-19 CVE-2021-41073 loop_rw_iter in fs/io_uring.c in the Linux kernel 5.10 through 5.14.6 allows local users to gain privileges by using IORING_OP_PROVIDE_BUFFERS to trigger a free of a kernel buffer, as demonstrated by using /proc/<pid>/maps for exploitation. Debian_linux, Fedora, Linux_kernel, Cloud_backup, H300e_firmware, H300s_firmware, H410c_firmware, H410s_firmware, H500e_firmware, H500s_firmware, H700e_firmware, H700s_firmware, Solidfire_baseboard_management_controller 7.8
