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