CVE-2020-26147 (GCVE-0-2020-26147)
Vulnerability from cvelistv5 – Published: 2021-05-11 19:40 – Updated: 2026-04-14 09:01
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.

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)
CWE
- CWE-362 - Race Condition (Concurrent Execution using Shared Resource with Improper Synchronization)

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
8.8 (High)

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.

CVE-2021-3506 (GCVE-0-2021-3506)
Vulnerability from cvelistv5 – Published: 2021-04-19 21:11 – Updated: 2024-08-03 16:53
VLAI
EPSS
Summary
An out-of-bounds (OOB) memory access flaw was found in fs/f2fs/node.c in the f2fs module in the Linux kernel in versions before 5.12.0-rc4. A bounds check failure allows a local attacker to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability.
Severity
No CVSS data available.
