Date Id Summary Products Score Patch Annotated
2021-03-05 CVE-2021-28039 An issue was discovered in the Linux kernel 5.9.x through 5.11.3, as used with Xen. In some less-common configurations, an x86 PV guest OS user can crash a Dom0 or driver domain via a large amount of I/O activity. The issue relates to misuse of guest physical addresses when a configuration has CONFIG_XEN_UNPOPULATED_ALLOC but not CONFIG_XEN_BALLOON_MEMORY_HOTPLUG. Linux_kernel, Cloud_backup, Solidfire_baseboard_management_controller_firmware, Xen 6.5
2021-04-08 CVE-2021-29154 BPF JIT compilers in the Linux kernel through 5.11.12 have incorrect computation of branch displacements, allowing them to execute arbitrary code within the kernel context. This affects arch/x86/net/bpf_jit_comp.c and arch/x86/net/bpf_jit_comp32.c. Debian_linux, Fedora, Linux_kernel, Cloud_backup, H300e_firmware, H300s_firmware, H410s_firmware, H500e_firmware, H500s_firmware, H700e_firmware, H700s_firmware, Hci_management_node, Solidfire 7.8
2021-04-20 CVE-2021-29155 An issue was discovered in the Linux kernel through 5.11.x. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory. Specifically, for sequences of pointer arithmetic operations, the pointer modification performed by the first operation is not correctly accounted for when restricting subsequent operations. Debian_linux, Fedora, Linux_kernel 5.5
2021-05-27 CVE-2021-33200 kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux->alu_limit. Fedora, Linux_kernel, Cloud_backup, H300e_firmware, H300s_firmware, H410s_firmware, H500e_firmware, H500s_firmware, H700e_firmware, H700s_firmware, Solidfire_\&_hci_management_node, Solidfire_baseboard_management_controller 7.8
2021-05-11 CVE-2021-32606 In the Linux kernel 5.11 through 5.12.2, isotp_setsockopt in net/can/isotp.c allows privilege escalation to root by leveraging a use-after-free. (This does not affect earlier versions that lack CAN ISOTP SF_BROADCAST support.) Fedora, Linux_kernel 7.8
2021-06-14 CVE-2021-34693 net/can/bcm.c in the Linux kernel through 5.12.10 allows local users to obtain sensitive information from kernel stack memory because parts of a data structure are uninitialized. Debian_linux, Linux_kernel 5.5
2021-07-21 CVE-2021-37159 hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free. Debian_linux, Linux_kernel, Communications_cloud_native_core_binding_support_function, Communications_cloud_native_core_network_exposure_function, Communications_cloud_native_core_policy 6.4
2021-10-20 CVE-2021-42739 The firewire subsystem in the Linux kernel through 5.14.13 has a buffer overflow related to drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandles bounds checking. Debian_linux, Fedora, Linux_kernel, Communications_cloud_native_core_binding_support_function, Communications_cloud_native_core_network_exposure_function, Communications_cloud_native_core_policy, Starwind_san_\&_nas, Starwind_virtual_san 6.7
2021-10-21 CVE-2021-42327 dp_link_settings_write in drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_debugfs.c in the Linux kernel through 5.14.14 allows a heap-based buffer overflow by an attacker who can write a string to the AMD GPU display drivers debug filesystem. There are no checks on size within parse_write_buffer_into_params when it uses the size of copy_from_user to copy a userspace buffer into a 40-byte heap buffer. Fedora, Linux_kernel, H300e_firmware, H300s_firmware, H410c_firmware, H410s_firmware, H500e_firmware, H500s_firmware, H700e_firmware, H700s_firmware 6.7
2021-11-17 CVE-2021-43976 In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic). Debian_linux, Fedora, Linux_kernel, Cloud_backup, H300e_firmware, H300s_firmware, H410c_firmware, H410s_firmware, H500e_firmware, H500s_firmware, H700e_firmware, H700s_firmware, Communications_cloud_native_core_binding_support_function, Communications_cloud_native_core_network_exposure_function, Communications_cloud_native_core_policy 4.6
