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.

Affected configurations

• linux linux kernel (>= 5.10.206 < 5.10.217) • linux linux kernel (>= 5.15.146 < 5.15.159) • linux linux kernel (>= 6.1.70 < 6.1.91) • linux linux kernel (>= 6.6.9 < 6.6.31) • linux linux kernel (>= 6.7 < 6.8.10) • linux linux kernel (>= 6.9 < 6.9.1)
