CVE-2024-36031

keys: Fix overwrite of key expiration on instantiation

State: Published
Severity: 9.8 Critical
Published: May 30, 2024
Updated: May 23, 2026
Reserved: May 17, 2024

Description

In the Linux kernel, the following vulnerability has been resolved:

keys: Fix overwrite of key expiration on instantiation

The expiry time of a key is unconditionally overwritten during instantiation, defaulting to turn it permanent. This causes a problem for DNS resolution as the expiration set by user-space is overwritten to TIME64_MAX, disabling further DNS updates. Fix this by restoring the condition that key_set_expiry is only called when the pre-parser sets a specific expiry.
