CVE-2023-52698
Calipso NetLabel Linux Kernel Memory Leak Vulnerability
Description
In the Linux kernel, the following vulnerability has been resolved: calipso: fix memory leak in netlbl_calipso_add_pass() If IPv6 support is disabled at boot (ipv6.disable=1), the calipso_init() -> netlbl_calipso_ops_register() function isn't called, and the netlbl_calipso_ops_get() function always returns NULL. In this case, the netlbl_calipso_add_pass() function allocates memory for the doi_def variable but doesn't free it with the calipso_doi_free().
