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

Si el estado no está inactivo, resolve_prepare_src() debería fallar inmediatamente y no debería ocurrir ningún cambio en el estado global. Sin embargo, sobrescribe incondicionalmente src_addr al intentar crear una dirección temporal. Por ejemplo, si el estado ya es RDMA_CM_LISTEN, esto dañará src_addr y provocará la prueba en cma_cancel_operation(): if (cma_any_addr(cma_src_addr(id_priv)) && !id_priv->cma_dev) Lo que se manifestaría como este rastro de syzkaller: ERROR : KASAN: use-after-free en __list_add_valid+0x93/0xa0 lib/list_debug.c:26 Lectura de tamaño 8 en addr ffff8881546491e0 por tarea syz-executor.1/32204 CPU: 1 PID: 32204 Comm: syz-executor.1 No contaminado 5.12.0-rc8-syzkaller #0 Nombre del hardware: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/01/2011 Seguimiento de llamadas: __dump_stack lib/dump_stack.c:79 [en línea] dump_stack+0x141/0x1d7 lib /dump_stack.c:120 print_address_description.constprop.0.cold+0x5b/0x2f8 mm/kasan/report.c:232 __kasan_report mm/kasan/report.c:399 [en línea] kasan_report.cold+0x7c/0xd8 mm/kasan/ report.c:416 __list_add_valid+0x93/0xa0 lib/list_debug.c:26 __list_add include/linux/list.h:67 [en línea] list_add_tail include/linux/list.h:100 [en línea] cma_listen_on_all drivers/infiniband/core/ cma.c:2557 [en línea] rdma_listen+0x787/0xe00 controladores/infiniband/core/cma.c:3751 ucma_listen+0x16a/0x210 controladores/infiniband/core/ucma.c:1102 ucma_write+0x259/0x350 controladores/infiniband/core /ucma.c:1732 vfs_write+0x28e/0xa30 fs/read_write.c:603 ksys_write+0x1ee/0x250 fs/read_write.c:658 do_syscall_64+0x2d/0x70 arch/x86/entry/common.c:46 Entry_SYSCALL_64_after_hwframe+0x44/ 0xae Esto indica que un rdma_id_private fue destruido sin realizar cma_cancel_listens().
