CVE-2021-44733 |
A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11. This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory object. Published: December 22, 2021; 12:15:09 PM -0500 |

CVE-2021-45100 |
The ksmbd server through 3.4.2, as used in the Linux kernel through 5.15.8, sometimes communicates in cleartext even though encryption has been enabled. This occurs because it sets the SMB2_GLOBAL_CAP_ENCRYPTION flag when using the SMB 3.1.1 protocol, which is a violation of the SMB protocol specification. When Windows 10 detects this protocol violation, it disables encryption. Published: December 16, 2021; 12:15:08 AM -0500 |

CVE-2020-27820 |
A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could happen if removing device (that is not common to remove video card physically without power-off, but same happens if "unbind" the driver). Published: November 02, 2021; 8:15:07 PM -0400 |
V4.0:(not available) V3.1: 4.7 MEDIUM V2.0: 4.7 MEDIUM |
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. Published: October 21, 2021; 1:15:07 PM -0400 |
V4.0:(not available) V3.1: 6.7 MEDIUM V2.0: 4.6 MEDIUM |
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. Published: October 20, 2021; 3:15:09 AM -0400 |
V4.0:(not available) V3.1: 6.7 MEDIUM V2.0: 4.6 MEDIUM |
CVE-2021-42252 |
An issue was discovered in aspeed_lpc_ctrl_mmap in drivers/soc/aspeed/aspeed-lpc-ctrl.c in the Linux kernel before 5.14.6. Local attackers able to access the Aspeed LPC control interface could overwrite memory in the kernel and potentially execute privileges, aka CID-b49a0e69a7b1. This occurs because a certain comparison uses values that are not memory sizes. Published: October 11, 2021; 3:15:07 PM -0400 |
V4.0:(not available) V3.1: 7.8 HIGH V2.0: 4.6 MEDIUM |
CVE-2021-42008 |
The decode_data function in drivers/net/hamradio/6pack.c in the Linux kernel before 5.13.13 has a slab out-of-bounds write. Input from a process that has the CAP_NET_ADMIN capability can lead to root access. Published: October 04, 2021; 8:15:07 PM -0400 |
V4.0:(not available) V3.1: 7.8 HIGH V2.0: 6.9 MEDIUM |
CVE-2021-41864 |

CVE-2021-3635 |
A flaw was found in the Linux kernel netfilter implementation in versions prior to 5.5-rc7. A user with root (CAP_SYS_ADMIN) access is able to panic the system when issuing netfilter netflow commands. Published: August 13, 2021; 10:15:07 AM -0400 |

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.
