CVE-2021-4028 (GCVE-0-2021-4028)

Vulnerability from cvelistv5 – Published: 2022-08-24 00:00 – Updated: 2024-08-03 17:16

Summary

A flaw in the Linux kernel's implementation of RDMA communications manager listener code allowed an attacker with local access to setup a socket to listen on a high port allowing for a list element to be used after free. Given the ability to execute code, a local attacker could leverage this use-after-free to crash the system or possibly escalate privileges on the system.

Severity ?

No CVSS data available.

CVE-2021-42717 (GCVE-0-2021-42717)

Vulnerability from cvelistv5 – Published: 2021-12-07 21:08 – Updated: 2024-08-04 03:38

Summary

ModSecurity 3.x through 3.0.5 mishandles excessively nested JSON objects. Crafted JSON objects with nesting tens-of-thousands deep could result in the web server being unable to service legitimate requests. Even a moderately large (e.g., 300KB) HTTP request can occupy one of the limited NGINX worker processes for minutes and consume almost all of the available CPU on the machine. Modsecurity 2 is similarly vulnerable: the affected versions include 2.8.0 through 2.9.4.

Severity ?

No CVSS data available.
