      "title": "RDMA/cma: Do not change route.addr.src_addr outside state checks",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/cma: Do not change route.addr.src_addr outside state checks\n\nIf the state is not idle then resolve_prepare_src() should immediately\nfail and no change to global state should happen. However, it\nunconditionally overwrites the src_addr trying to build a temporary any\naddress.\n\nFor instance if the state is already RDMA_CM_LISTEN then this will corrupt\nthe src_addr and would cause the test in cma_cancel_operation():\n\n           if (cma_any_addr(cma_src_addr(id_priv)) && !id_priv->cma_dev)\n\nWhich would manifest as this trace from syzkaller:\n\n  BUG: KASAN: use-after-free in __list_add_valid+0x93/0xa0 lib/list_debug.c:26\n  Read of size 8 at addr ffff8881546491e0 by task syz-executor.1/32204\n\n  CPU: 1 PID: 32204 Comm: syz-executor.1 Not tainted 5.12.0-rc8-syzkaller #0\n  Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/01/2011\n  Call Trace:\n   __dump_stack lib/dump_stack.c:79 [inline]\n   dump_stack+0x141/0x1d7 lib/dump_stack.c:120\n   print_address_description.constprop.0.cold+0x5b/0x2f8 mm/kasan/report.c:232\n   __kasan_report mm/kasan/report.c:399 [inline]\n   kasan_report.cold+0x7c/0xd8 mm/kasan/report.c:416\n   __list_add_valid+0x93/0xa0 lib/list_debug.c:26\n   __list_add include/linux/list.h:67 [inline]\n   list_add_tail include/linux/list.h:100 [inline]\n   cma_listen_on_all drivers/infiniband/core/cma.c:2557 [inline]\n   rdma_listen+0x787/0xe00 drivers/infiniband/core/cma.c:3751\n   ucma_listen+0x16a/0x210 drivers/infiniband/core/ucma.c:1102\n   ucma_write+0x259/0x350 drivers/infiniband/core/ucma.c:1732\n   vfs_write+0x28e/0xa30 fs/read_write.c:603\n   ksys_write+0x1ee/0x250 fs/read_write.c:658\n   do_syscall_64+0x2d/0x70 arch/x86/entry/common.c:46\n   entry_SYSCALL_64_after_hwframe+0x44/0xae\n\nThis is indicating that an rdma_id_private was destroyed without doing\ncma_cancel_listens().\n\nInstead of trying to re-use the src_addr memory to indirectly create an\nany address derived from the dst build one explicitly on the stack and\nbind to that as any other normal flow would do. rdma_bind_addr() will copy\nit over the src_addr once it knows the state is valid.\n\nThis is similar to commit bc0bdc5afaa7 (\"RDMA/cma: Do not change\nroute.addr.src_addr.ss_family\")",
