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 |

The Transparent Inter-Process Communication (TIPC) functionality allows remote attackers to exploit insufficient validation of user-supplied sizes for the MSG_CRYPTO message type. Published: November 02, 2021; 7:15:07 PM -0400 |
V4.0:(not available) V3.1: 9.8 CRITICAL V2.0: 7.5 HIGH |
CVE-2021-43057 |
An issue was discovered in the Linux kernel before 5.14.8. A use-after-free in selinux_ptrace_traceme (aka the SELinux handler for PTRACE_TRACEME) could be used by local attackers to cause memory corruption and escalate privileges, aka CID-a3727a8bac0a. This occurs because of an attempt to access the subjective credentials of another task. Published: October 28, 2021; 12:15:08 AM -0400 |
V4.0:(not available) V3.1: 7.8 HIGH V2.0: 7.2 HIGH |
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 |
