{"id":"DEBIAN-CVE-2024-36476","details":"In the Linux kernel, the following vulnerability has been resolved:  RDMA/rtrs: Ensure 'ib_sge list' is accessible  Move the declaration of the 'ib_sge list' variable outside the 'always_invalidate' block to ensure it remains accessible for use throughout the function.  Previously, 'ib_sge list' was declared within the 'always_invalidate' block, limiting its accessibility, then caused a 'BUG: kernel NULL pointer dereference'[1].  ? __die_body.cold+0x19/0x27  ? page_fault_oops+0x15a/0x2d0  ? search_module_extables+0x19/0x60  ? search_bpf_extables+0x5f/0x80  ? exc_page_fault+0x7e/0x180  ? asm_exc_page_fault+0x26/0x30  ? memcpy_orig+0xd5/0x140  rxe_mr_copy+0x1c3/0x200 [rdma_rxe]  ? rxe_pool_get_index+0x4b/0x80 [rdma_rxe]  copy_data+0xa5/0x230 [rdma_rxe]  rxe_requester+0xd9b/0xf70 [rdma_rxe]  ? finish_task_switch.isra.0+0x99/0x2e0  rxe_sender+0x13/0x40 [rdma_rxe]  do_task+0x68/0x1e0 [rdma_rxe]  process_one_work+0x177/0x330  worker_thread+0x252/0x390  ? __pfx_worker_thread+0x10/0x10  This change ensures the variable is available for subsequent operations that require it.
