zram->comp_algs[ZRAM_PRIMARY_COMP] can be NULL in zram_add() if comp_algorithm_set() has not been called.
User can access the zram device by sysfs after device_add_disk(), so there is a time window to trigger the
NULL pointer dereference. Move it ahead device_add_disk() to make sure when user can access the zram
device, it is ready. comp_algorithm_set() is protected by zram->init_lock in other places and no such
problem. (CVE-2024-53222)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18613.263.4 or later.
