Description

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Don't 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: [] stack_top+0x58/0xa8 [] arch_pick_mmap_layout+0x164/0x220 [] kunit_vm_mmap_init+0x108/0x12c [] __kunit_add_resource+0x38/0x8c [] kunit_vm_mmap+0x88/0xc8 […
