CVE-2021-33033

Published: 14 May 2021

The Linux kernel before 5.11.14 has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. This leads to writing an arbitrary value.

From the Ubuntu Security Team

It was discovered that the CIPSO implementation in the Linux kernel did not properly perform reference counting in some situations, leading to use- after-free vulnerabilities. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
