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. Published: July 20, 2021; 3:15:09 PM -0400 |

CVE-2021-35039 |
kernel/module.c in the Linux kernel before 5.12.14 mishandles Signature Verification, aka CID-0c18f29aae7c.

V4.0:(not available) V3.1: 7.8 HIGH V2.0: 6.9 MEDIUM |
CVE-2021-33624 |
In kernel/bpf/verifier.c in the Linux kernel before 5.12.13, a branch can be mispredicted (e.g., because of type confusion) and consequently an unprivileged BPF program can read arbitrary memory locations via a side-channel attack, aka CID-9183671af6db. Published: June 23, 2021; 12:15:07 PM -0400 |
V4.0:(not available) V3.1: 4.7 MEDIUM V2.0: 4.7 MEDIUM |
CVE-2021-32078 |
An Out-of-Bounds Read was discovered in arch/arm/mach-footbridge/personal-pci.c in the Linux kernel through 5.12.11 because of the lack of a check for a value that shouldn't be negative, e.g., access to element -2 of an array, aka CID-298a58e165e4. Published: June 17, 2021; 11:15:07 AM -0400 |
V4.0:(not available) V3.1: 7.1 HIGH V2.0: 6.6 MEDIUM |
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. Published: June 14, 2021; 6:15:20 PM -0400 |
V4.0:(not available) V3.1: 5.5 MEDIUM V2.0: 2.1 LOW |
CVE-2021-3564 |
A flaw double-free memory corruption in the Linux kernel HCI device initialization subsystem was found in the way user attach malicious HCI TTY Bluetooth device.

V4.0:(not available) V3.1: 5.5 MEDIUM V2.0: 2.1 LOW |
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. Published: May 27, 2021; 9:15:08 AM -0400 |
V4.0:(not available) V3.1: 7.8 HIGH V2.0: 7.2 HIGH |

CVE-2020-26558 |
Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this attacker to complete authenticated pairing with the responding device using the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit at a time. Published: May 24, 2021; 2:15:07 PM -0400 |
V4.0:(not available) V3.1: 4.2 MEDIUM V2.0: 4.3 MEDIUM |
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.) Published: May 11, 2021; 7:15:09 PM -0400 |
V4.0:(not available) V3.1: 7.8 HIGH V2.0: 7.2 HIGH |
CVE-2020-26147 |
An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. Published: May 11, 2021; 4:15:08 PM -0400 |
V4.0:(not available) V3.1: 5.4 MEDIUM V2.0: 3.2 LOW |
CVE-2020-24588 |
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated. Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets. Published: May 11, 2021; 4:15:08 PM -0400 |
V4.0:(not available) V3.1: 3.5 LOW V2.0: 2.9 LOW |
CVE-2020-24587 |
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP encryption key is periodically renewed. Published: May 11, 2021; 4:15:08 PM -0400 |
V4.0:(not available) V3.1: 2.6 LOW V2.0: 1.8 LOW |
CVE-2020-24586 |
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.

V4.0:(not available) V3.1: 3.5 LOW V2.0: 2.9 LOW |
CVE-2021-20194 |
There is a vulnerability in the linux kernel versions higher than 5.2 (if kernel compiled with config params CONFIG_BPF_SYSCALL=y , CONFIG_BPF=y , CONFIG_CGROUPS=y , CONFIG_CGROUP_BPF=y , CONFIG_HARDENED_USERCOPY not set, and BPF hook to getsockopt is registered). As result of BPF execution, the local user can trigger bug in __cgroup_bpf_run_filter_getsockopt() function that can lead to heap overflow (because of non-hardened usercopy). The impact of attack could be deny of service or possibly privileges escalation. Published: February 23, 2021; 6:15:13 PM -0500 |

CVE-2019-3016 |
In a Linux KVM guest that has PV TLB enabled, a process in the guest kernel may be able to read memory locations from another process in the same guest. This problem is limit to the host running linux kernel 4.10 with a guest running linux kernel 4.16 or later. The problem mainly affects AMD processors but Intel CPUs cannot be ruled out.

CVE-2019-3887 |
A flaw was found in the way KVM hypervisor handled x2APIC Machine Specific Rregister (MSR) access with nested(=1) virtualization enabled.
