Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Race condition
EUVDB-ID: #VU112445
Risk: Medium
CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:L/VI:L/VA:N/SC:L/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2025-52496
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to a race condition on x86 and amd64 systems that have the AESNI instruction, as it can be used for AES encryption and decryption. A remote attacker can extract AES keys from multithreaded programs and use them to decrypt traffic.
MitigationInstall updates from vendor's repository.
Vulnerable software versionsFedora: 10
mbedtls: before 3.6.4-2.el10_0
CPE2.3 External linkshttps://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2025-4a35036fc1
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Out-of-bounds read
EUVDB-ID: #VU112444
Risk: Medium
CVSSv4.0: 6.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2025-52497
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when parsing invalid PEM-encrypted material in mbedtls_pk_parse_key(), mbedtls_pk_parse_keyfile() and mbedtls_pem_read_buffer() functions. A remote attacker can pass specially crafted data to the application, trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service attack.
MitigationInstall updates from vendor's repository.
