Description

In the Linux kernel, the following vulnerability has been resolved: s390/bpf: Fix bpf_plt pointer arithmetic Kui-Feng Lee reported a crash on s390x triggered by the dummy_st_ops/dummy_init_ptr_arg test [1]: [] 0x2 [] bpf_struct_ops_test_run+0x156/0x250 [] __sys_bpf+0xa1a/0xd00 [] __s390x_sys_bpf+0x44/0x50 [] __do_syscall+0x244/0x300 [] system_call+0x70/0x98 This is caused by GCC moving memcpy() after assignments in bpf_jit_plt(), resulting in NULL pointers being written instead of the return
