CVE-2020-26139 (GCVE-0-2020-26139)
Vulnerability from cvelistv5 – Published: 2021-05-11 19:37 – Updated: 2024-08-04 15:49
VLAI?
EPSS
Summary
An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients.
Severity ?
No CVSS data available.

EPSS
Summary
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.
Severity ?
No CVSS data available.

CVE-2020-26146 (GCVE-0-2020-26146)
Vulnerability from cvelistv5 – Published: 2021-05-11 19:39 – Updated: 2024-08-04 15:49
VLAI?
EPSS
Summary
An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WPA, WPA2, and WPA3 implementations reassemble fragments with non-consecutive packet numbers. An adversary can abuse this to exfiltrate selected fragments. This vulnerability is exploitable when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used. Note that WEP is vulnerable to this attack by design.
Severity ?
No CVSS data available.

CVE-2021-29155 (GCVE-0-2021-29155)
Vulnerability from cvelistv5 – Published: 2021-04-20 00:00 – Updated: 2024-08-03 22:02
VLAI?
EPSS
Summary
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.
Severity ?
No CVSS data available.

CVE-2021-31440 (GCVE-0-2021-31440)
Vulnerability from cvelistv5 – Published: 2021-05-21 14:30 – Updated: 2024-08-03 22:55
VLAI?
EPSS
Summary
This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel 5.11.15. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of eBPF programs. The issue results from the lack of proper validation of user-supplied eBPF programs prior to executing them. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel. Was ZDI-CAN-13661.
Severity ?

Title
Linux Kernel sctp_destroy_sock race condition
Summary
A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket.
Severity ?
6.7 (Medium)

CVE-2020-26144 (GCVE-0-2020-26144)
Vulnerability from cvelistv5 – Published: 2021-05-11 19:33 – Updated: 2024-08-04 15:49
VLAI?
EPSS
Summary
An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept plaintext A-MSDU frames as long as the first 8 bytes correspond to a valid RFC1042 (i.e., LLC/SNAP) header for EAPOL. An adversary can abuse this to inject arbitrary network packets independent of the network configuration.
Severity ?
No CVSS data available.

Title
Linux kernel eBPF RINGBUF map oversized allocation
Summary
The eBPF RINGBUF bpf_ringbuf_reserve() function in the Linux kernel did not check that the allocated size was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel and therefore, arbitrary code execution. This issue was fixed via commit 4b81ccebaeee ("bpf, ringbuf: Deny reserve of buffers larger than ringbuf") (v5.13-rc4) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was introduced via 457f44363a88 ("bpf: Implement BPF ring buffer and verifier support for it") (v5.8-rc1).

CVE-2020-26147 (GCVE-0-2020-26147)
Vulnerability from cvelistv5 – Published: 2021-05-11 19:40 – Updated: 2024-08-04 15:49
VLAI?
EPSS
Summary
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.
Severity ?
No CVSS data available.

Summary
An issue was discovered in the Linux kernel before 5.11.11. The netfilter subsystem allows attackers to cause a denial of service (panic) because net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h lack a full memory barrier upon the assignment of a new table value, aka CID-175e476b8cdf.
Severity ?
No CVSS data available.

CVE-2020-24586 (GCVE-0-2020-24586)
Vulnerability from cvelistv5 – Published: 2021-05-11 00:00 – Updated: 2024-08-04 15:19
VLAI?
EPSS
Summary
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.
Severity ?
No CVSS data available.

VLAI?
EPSS
Summary
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.
Severity ?
No CVSS data available.

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.
Severity ?
No CVSS data available.

CVE-2021-31829 (GCVE-0-2021-31829)
Vulnerability from cvelistv5 – Published: 2021-05-06 15:43 – Updated: 2024-08-03 23:10
VLAI?
EPSS
Summary
kernel/bpf/verifier.c in the Linux kernel through 5.12.1 performs undesirable speculative loads, leading to disclosure of stack content via side-channel attacks, aka CID-801c6058d14a. The specific concern is not protecting the BPF stack area against speculative loads. Also, the BPF stack can contain uninitialized data that might represent sensitive information previously operated on by the kernel.
Severity ?
No CVSS data available.

CVE-2021-33200 (GCVE-0-2021-33200)
Vulnerability from cvelistv5 – Published: 2021-05-27 00:00 – Updated: 2024-08-03 23:42
VLAI?
EPSS
Summary
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.
Severity ?
No CVSS data available.
