      "title": "netfilter: nf_tables: fix dst corruption in same register operation",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: nf_tables: fix dst corruption in same register operation\n\nFor lshift and rshift, the shift operations are performed in a loop over\n32-bit words. The loop calculates the shifted value and write it to dst,\nand then immediately reads from src to calculate the carry for the next\niteration. Because src and dst could point to the same memory location,\nthe carry is incorrectly calculated using the newly modified dst value\ninstead of the original src value.\n\nAdding a temporary local variable to cache the original value before\nwriting to dst and using it for the carry calculation solves the\nproblem. In addition, partial overlap is rejected from control plane for\nall kind of operations including byteorder. This was tested with the\nfollowing bytecode:\n\ntable test_table ip flags 0 use 1 handle 1\nip test_table test_chain use 3 type filter hook input prio 0 policy accept packets 0 bytes 0 flags 1\nip test_table test_chain 2\n  [ immediate reg 1 0x44332211 0x88776655 ]\n  [ bitwise reg 1 = ( reg 1 << 0x08000000 ) ]\n  [ cmp eq reg 1 0x66443322 0x00887766 ]\n  [ counter pkts 0 bytes 0 ]\nip test_table test_chain 4 3\n  [ immediate reg 1 0x44332211 0x88776655 ]\n  [ bitwise reg 1 = ( reg 1 << 0x08000000 ) ]\n  [ cmp eq reg 1 0x55443322 0x00887766 ]\n  [ counter pkts 21794 bytes 1917798 ]",
