To simply fix it, we could just pass @sign kmalloc'd from crypt_message() and then we're done. Luckily, we don't seem to pass any other vmalloc'd buffers in smb_rqst::rq_iov... Instead, let's map the correct pages and offsets from vmalloc buffers as well in cifs_sg_set_buf() and then avoiding such oopses. (CVE-2022-50341)

  - 已修复 Linux 内核中的下列漏洞：mt76: mt7915: Fix PCI device refcount leak in mt7915_pci_init_hif2() As comment of pci_get_device() says, it returns a pci_device with its refcount increased. We need to call pci_dev_put() to decrease the refcount. Save the return value of pci_get_device() and call pci_dev_put() to decrease the refcount. (CVE-2022-50464)

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 已修复 Linux 内核中的下列漏洞：scsi: iscsi_tcp: Check that sock is valid before iscsi_set_param() The validity of sock should be checked before assignment to avoid incorrect values. Commit 57569c37f0ad (scsi: iscsi: iscsi_tcp: Fix null-ptr-deref while calling getpeername()) introduced this change which may lead to inconsistent values of tcp_sw_conn->sendpage and conn->datadgst_en. Fix the issue by moving the position of the assignment. (CVE-2023-53464)
