Exploitation evidence

Disclosed: evidence found.
CVE published 7 May 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 10 Nov 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.

Description

This update for openCryptoki fixes the following issues Security issue: - CVE-2026-40253: Updated fix for malformed BER-encoded cryptographic objects (bsc#1262283). Non security issue: - Refactored .spec file to fully support transactional and immutable operating systems (jsc#PED-14609): * Migrated user and group creation (pkcs11, pkcsslotd) from imperative %pre shell commands to declarative systemd-sysusers configuration. * Replaced manual /var directory tracking and %ghost directives with comprehensive systemd-tmpfiles configurations. * Implemented dynamic, architecture-specific tmpfiles.d generation to properly provision hardware-specific token directories (e.g., ccatok, ep11tok, lite, and HSM_MK_CHANGE). - Fixed permissions for /run/opencryptoki within tmpfiles.d to ensure the daemon can successfully drop privileges and bind its communication socket. * Moved 32-bit and 64-bit shared library symlink creation (such as PKCS11_API.so, stdll, and methods) from %post scriptlets into the %install phase, ensuring they are correctly packaged and tracked on the read-only /usr partition. * Removed legacy /etc/pkcs11 bash migration logic from %post, replacing it with a declarative tmpfiles.d symlink rule. - Cleaned up scriptlets to only execute transaction-safe macros (such as ldconfig and systemd service handlers).
