Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

cryptoki versions before 0.10.1, from 0.11.0 before 0.11.1, and from 0.12.0 before 0.12.1 are affected. When Session::get_attributes returns a nonempty CKA_ALLOWED_MECHANISMS attribute, the library builds an out-of-bounds slice, which can cause undefined behavior, a crash, or possible disclosure of nearby heap data. Upgrade to 0.10.1, 0.11.1, or 0.12.1, matching your release line. The source gives no details on whether an attacker must control the token or session contents.
