| Doc Text: |
A flaw was found in the Linux kernel, where the management of inter-process communication uses AF_UNIX sockets. The issue arises from a race condition where a partially initialized socket with specific permissions carrying SCM_RIGHTS is improperly handled during garbage collection. This situation leads to an incorrect count of active sockets, potentially causing resources to remain unaccounted for and never released.
