DescriptionIn the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix slab-use-after-free Read in rxe_queue_cleanup bug Call Trace: <TASK> __dump_stack lib/dump_stack.c:94 [inline] dump_stack_lvl+0x7d/0xa0 lib/dump_stack.c:120 print_address_description mm/kasan/report.c:378 [inline] print_report+0xcf/0x610 mm/kasan/report.c:489 kasan_report+0xb5/0xe0 mm/kasan/report.c:602 rxe_queue_cleanup+0xd0/0xe0 drivers/infiniband/sw/rxe/rxe_queue.c:195 rxe_cq_cleanup+0x3f/0x50 drivers/infiniband/sw/rxe/rxe_cq.c:132 __rxe_cleanup+0x168/0x300 drivers/infiniband/sw/rxe/rxe_pool.c:232 rxe_create_cq+0x22e/0x3a0 drivers/infiniband/sw/rxe/rxe_verbs.c:1109 create_cq+0x658/0xb90 drivers/infiniband/core/uverbs_cmd.c:1052 ib_uverbs_create_cq+0xc7/0x120 drivers/infiniband/core/uverbs_cmd.c:1095 ib_uverbs_write+0x969/0xc90 drivers/infiniband/core/uverbs_main.c:679 vfs_write fs/read_write.c:677 [inline] vfs_write+0x26a/0xcc0 fs/read_write.c:659 ksys_write+0x1b8/0x200 fs/read_write.c:731 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xaa/0x1b0 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x77/0x7f In the function rxe_create_cq, when rxe_cq_from_init fails, the function rxe_cleanup will be called to handle the allocated resources. In fact, some memory resources have already been freed in the function rxe_cq_from_init. Thus, this problem will occur. The solution is to let rxe_cleanup do all the work.
