In versions 0.6.12 and prior, the pam_pkcs11 module segfaults when a user presses ctrl-c/ctrl-d when they are asked for a PIN. When a user enters no PIN at all, `pam_get_pwd` will never initialize the password buffer pointer and as such `cleanse` will try to dereference an uninitialized pointer. On my system this pointer happens to have the value 3 most of the time when running sudo and as such it will segfault. The most likely impact to a system affected by this issue is an availability impact due to a daemon that uses PAM crashing. As of time of publication, a patch for the issue is unavailable.","title":"CVE description"}],"product_status":{"recommended":["SUSE Linux Enterprise Server LTSS Extended Security 12 SP5:pam_pkcs11-0.6.8-7.8.1.x86_64","SUSE Linux Enterprise Server LTSS Extended Security 12 SP5:pam_pkcs11-32bit-0.6.8-7.8.1.x86_64"]},"references":[{"category":"external","summary":"CVE-2025-24031","url":"https://www.suse.com/security/cve/CVE-2025-24031"},{"category":"external","summary":"SUSE Bug 1237058 for CVE-2025-24031","url":"https://bugzilla.suse.com/1237058"}],"remediations":[{"category":"vendor_fix","details":"To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n","product_ids":["SUSE Linux Enterprise Server LTSS Extended Security 12 SP5:pam_pkcs11-0.6.8-7.8.1.x86_64","SUSE Linux Enterprise Server LTSS Extended Security 12 SP5:pam_pkcs11-32bit-0.6.8-7.8.1.x86_64"]}],"scores":[{"cvss_v3":{"baseScore":3.3,"baseSeverity":"LOW","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L","version":"3.1"},"products":["SUSE Linux Enterprise Server LTSS Extended Security 12 SP5:pam_pkcs11-0.6.8-7.8.1.x86_64","SUSE Linux Enterprise Server LTSS Extended Security 12 SP5:pam_pkcs11-32bit-0.6.8-7.8.1.x86_64"]}],"threats":[{"category":"impact","date":"2025-02-24T12:55:41Z","details":"moderate"}],"title":"CVE-2025-24031"},{"cve":"CVE-2025-24032","ids":[{"system_name":"SUSE CVE Page","text":"https://www.suse.com/security/cve/CVE-2025-24032"}],"notes":[{"category":"general","text":"PAM-PKCS#11 is a Linux-PAM login module that allows a X.509 certificate based user login.

An attacker may create a different token with the user's public data (e.g. the user's certificate) and a PIN known to the attacker. If no signature with the private key is required, then the attacker may now login as user with that created token.
