In the Linux kernel, the following vulnerability has been resolved:
RDMA/core: Fix null-ptr-deref in ib_core_cleanup()
KASAN reported a null-ptr-deref error:
KASAN: null-ptr-deref in range [0x0000000000000118-0x000000000000011f]
CPU: 1 PID: 379
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996)
RIP: 0010:destroy_workqueue+0x2f/0x740
RSP: 0018:ffff888016137df8 EFLAGS: 00000202
...
Call Trace:
ib_core_cleanup+0xa/0xa1 [ib_core]
__do_sys_delete_module.constprop.0+0x34f/0x5b0
do_syscall_64+0x3a/0x90
entry_SYSCALL_64_after_hwframe+0x63/0xcd
RIP: 0033:0x7fa1a0d221b7
...
It is because the fail of roce_gid_mgmt_init() is ignored:
ib_core_init()
roce_gid_mgmt_init()
gid_cache_wq = alloc_ordered_workqueue # fail
...
ib_core_cleanup()
roce_gid_mgmt_cleanup()
destroy_workqueue(gid_cache_wq)
# destroy an unallocated wq
Fix this by catching the fail of roce_gid_mgmt_init() in ib_core_init().
