net: Fix TOCTOU race condition in unix_conf_op #2413

Closed avagin closed 1 month ago

avagin commented 1 month ago

The unix_conf_op function reads the size of the sysctl entry array twice. gcc thinks that it can lead to a time-of-check to time-of-use (TOCTOU) race condition if the array size changes between the two reads.

Fixes #2398
