Luckily, we don&amp;#39;t seem to pass<br /> any other vmalloc&amp;#39;d buffers in smb_rqst::rq_iov...<br /> <br /> Instead, let&amp;#39;s map the correct pages and offsets from vmalloc buffers<br /> as well in cifs_sg_set_buf() and then avoiding such oopses.

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> rapidio: fix possible name leaks when rio_add_device() fails<br /> <br /> Patch series "rapidio: fix three possible memory leaks".<br /> <br /> This patchset fixes three name leaks in error handling.<br /> - patch #1 fixes two name leaks while rio_add_device() fails.<br /> - patch #2 fixes a name leak while rio_register_mport() fails.<br /> <br /> <br /> This patch (of 2):<br /> <br /> If rio_add_device() returns error, the name allocated by dev_set_name()<br /> need be freed. It should use put_device() to give up the reference in the<br /> error path, so that the name can be freed in kobject_cleanup(), and the<br /> &amp;#39;rdev&amp;#39; can be freed in rio_release_dev().

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Bluetooth: avoid hci_dev_test_and_set_flag() in mgmt_init_hdev()<br /> <br /> syzbot is again reporting attempt to cancel uninitialized work<br /> at mgmt_index_removed() [1], for setting of HCI_MGMT flag from<br /> mgmt_init_hdev() from hci_mgmt_cmd() from hci_sock_sendmsg() can<br /> race with testing of HCI_MGMT flag from mgmt_index_removed() from<br /> hci_sock_bind() due to lack of serialization via hci_dev_lock().<br /> <br /> Since mgmt_init_hdev() is called with mgmt_chan_list_lock held, we can<br /> safely split hci_dev_test_and_set_flag() into hci_dev_test_flag() and<br /> hci_dev_set_flag(). Thus, in order to close this race, set HCI_MGMT flag<br /> after INIT_DELAYED_WORK() completed.<br /> <br /> This is a local fix based on mgmt_chan_list_lock. Lack of serialization<br /> via hci_dev_lock() might be causing different race conditions somewhere<br /> else. But a global fix based on hci_dev_lock() should deserve a future<br /> patch.

*** Pendiente de traducción *** WebAssembly Micro Runtime (WAMR) is a lightweight standalone WebAssembly (Wasm) runtime. In WAMR versions prior to 2.4.2, when running in LLVM-JIT mode, the runtime cannot exit normally when executing WebAssembly programs containing a memory.fill instruction where the first operand (memory address pointer) is greater than or equal to 2147483648 bytes (2GiB). This causes the runtime to hang in release builds or crash in debug builds due to accessing an invalid pointer. The issue does not occur in FAST-JIT mode or other runtime tools. This has been fixed in version 2.4.2.
