Title
Clevis: clevis: no authentication on pkcs#11 af_unix sockets allows key injection under permissive umask
Summary
A flaw was found in the clevis PKCS#11 pin. The clevis-pkcs11-afunix-socket-unlock daemon creates AF_UNIX sockets without explicit permission restrictions or peer credential verification. Under a permissive process umask, any local user can connect to the control socket and inject arbitrary device/key pairs, or connect to the data socket to receive LUKS passphrases.
Severity

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
