  "description": "In the Linux kernel, the following vulnerability has been resolved:  LoongArch: Don\u0027t crash in stack_top() for tasks without vDSO  Not all tasks have a vDSO mapped, for example kthreads never do. If such a task ever ends up calling stack_top(), it will derefence the NULL vdso pointer and crash.  This can for example happen when using kunit:  \t[\u003C9000000000203874\u003E] stack_top\u002B0x58/0xa8 \t[\u003C90000000002956cc\u003E] arch_pick_mmap_layout\u002B0x164/0x220 \t[\u003C90000000003c284c\u003E] kunit_vm_mmap_init\u002B0x108/0x12c \t[\u003C90000000003c1fbc\u003E] __kunit_add_resource\u002B0x38/0x8c \t[\u003C90000000003c2704\u003E] kunit_vm_mmap\u002B0x88/0xc8 \t[\u003C9000000000410b14\u003E] usercopy_test_init\u002B0xbc/0x25c \t[\u003C90000000003c1db4\u003E] kunit_try_run_case\u002B0x5c/0x184 \t[\u003C90000000003c3d54\u003E] kunit_generic_run_threadfn_adapter\u002B0x24/0x48 \t[\u003C900000000022e4bc\u003E] kthread\u002B0xc8/0xd4 \t[\u003C9000000000200ce8\u003E] ret_from_kernel_thread\u002B0xc/0xa4",
