It was discovered that Mbed TLS incorrectly handled memory allocation failures. A remote attacker could possibly use this issue to crash the program. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2021-44732)

Jonathan Winzig discovered that Mbed TLS incorrectly handled crafted inputs. A remote attacker could possibly use this issue to crash the program, resulting in a denial of service. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS. (CVE-2024-23775)

It was discovered that Mbed TLS incorrectly handled the TLS handshake. A remote attacker could possibly use this issue to break the security guarantees of the TLS handshake. (CVE-2025-27810)

Linh Le and Ngan Nguyen discovered that Mbed TLS incorrectly documented the behavior of a function. Application code relying on the documented behavior might be affected. A remote attacker could possibly use this issue to execute arbitrary code. (CVE-2025-47917)

Linh Le and Ngan Nguyen discovered that Mbed TLS incorrectly handled crafted input. A remote attacker could possibly use this issue to crash the program, resulting in a denial of service. (CVE-2025-48965)

It was discovered that Mbed TLS incorrectly handled a race condition. An attacker could possibly use this issue to extract AES keys. (CVE-2025-52496)

Linh Le and Ngan Nguyen discovered that Mbed TLS incorrectly handled certain invalid input. A remote attacker could possibly use this issue to crash the program, resulting in a denial of service. (CVE-2025-52497)
