Exploitation evidence

Disclosed: evidence found.
CVE published 10 Jul 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 31 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

A security update for python-cryptography has been released that addresses these vulnerabilities. Users should apply the official update from the SUSE Product Security Team or their respective package maintainers to remediate these issues. Since this is not a cloud service, remediation depends on applying the patch. Patch status is not explicitly confirmed in the provided data; users should consult the vendor advisory for the latest remediation guidance.

Description

This security update for python-cryptography addresses multiple vulnerabilities related to OpenSSL, including buffer overflows, out-of-bounds reads and writes, memory leaks, and undefined behavior in certificate handling. These issues affect cryptographic operations such as key derivation, password callbacks, AES key wrapping, and message digest finalization. The vulnerabilities have been assigned CVE identifiers ranging from CVE-2026-41676 to CVE-2026-45784. No specific affected versions are stated in the provided data.

Impact

The vulnerabilities can lead to memory corruption issues such as buffer overflows and out-of-bounds reads/writes, which may cause crashes, data leaks, or potentially allow attackers to manipulate cryptographic operations. The memory leak vulnerability could expose adjacent memory contents to the network, risking sensitive data exposure. Undefined behavior in certificate processing may affect validation or response handling. No confirmed exploits in the wild are reported.

Summary

The python-cryptography package update fixes several OpenSSL-related security flaws: CVE-2026-41676 and CVE-2026-41677 involve buffer overflow and out-of-bounds read issues in key derivation and PEM password callbacks; CVE-2026-41678 and CVE-2026-45784 address out-of-bounds writes due to incorrect buffer sizing in AES key unwrap and cipher update operations; CVE-2026-41681 concerns a buffer overwrite in digest finalization without length checks; CVE-2026-41898 involves memory leakage through unchecked callback lengths in PSK and cookie generation; CVE-2026-42327 describes undefined behavior with non-UTF-8 OCSP URLs in certificates; CVE-2026-44662 reports a heap buffer overflow during AES key wrap with padding encryption. These vulnerabilities collectively pose risks of memory corruption and potential information leakage in cryptographic functions.
