  - 已修复 Linux 内核中的下列漏洞：wifi: ath9k: avoid uninit memory read in ath9k_htc_rx_msg() syzbot is reporting uninit value at ath9k_htc_rx_msg() [1], for ioctl(USB_RAW_IOCTL_EP_WRITE) can call ath9k_hif_usb_rx_stream() with pkt_len = 0 but ath9k_hif_usb_rx_stream() uses __dev_alloc_skb(pkt_len + 32, GFP_ATOMIC) based on an assumption that pkt_len is valid. As a result, ath9k_hif_usb_rx_stream() allocates skb with uninitialized memory and ath9k_htc_rx_msg() is reading from uninitialized memory. Since bytes accessed by ath9k_htc_rx_msg() is not known until ath9k_htc_rx_msg() is called, it would be difficult to check minimal valid pkt_len at if (pkt_len > 2 * MAX_RX_BUF_SIZE) { line in ath9k_hif_usb_rx_stream(). We have two choices. One is to workaround by adding __GFP_ZERO so that ath9k_htc_rx_msg() sees 0 if pkt_len is invalid. The other is to let ath9k_htc_rx_msg() validate pkt_len before accessing. This patch chose the latter. Note that I'm not sure threshold condition is correct, for I can't find details on possible packet length used by this protocol. (CVE-2022-50709)

  - 已修复 Linux 内核中的下列漏洞：configfs: fix possible memory leak in configfs_create_dir() kmemleak reported memory leaks in configfs_create_dir(): unreferenced object 0xffff888009f6af00 (size 192): comm modprobe, pid 3777, jiffies 4295537735 (age 233.784s) backtrace:

This is because the refcount is not correct in configfs_make_dirent(). For normal stage, the refcount is changing as: configfs_register_subsystem() configfs_create_dir() configfs_make_dirent() configfs_new_dirent() # set s_count = 1 dentry->d_fsdata = configfs_get(sd); # s_count = 2 ... configfs_unregister_subsystem() configfs_remove_dir() remove_dir() configfs_remove_dirent() # s_count = 1 dput() ...
    *dentry_unlink_inode()* configfs_d_iput() # s_count = 0, release However, if we failed in configfs_create(): configfs_register_subsystem() configfs_create_dir() configfs_make_dirent() # s_count = 2 ... configfs_create() # fail ->out_remove: configfs_remove_dirent(dentry) configfs_put(sd) # s_count = 1 return PTR_ERR(inode); There is no inode in the error path, so the configfs_d_iput() is lost and makes sd and fragment memory leaked. To fix this, when we failed in configfs_create(), manually call configfs_put(sd) to keep the refcount correct. (CVE-2022-50751)

    __memcpy+0x110/0x260 read_kcore+0x584/0x778 proc_reg_read+0xb4/0xe4 During early boot, memblock reserves the pages for the ramoops reserved memory node in DT that would otherwise be part of the direct lowmem mapping. Pstore's ram backend reuses those reserved pages to change the memory type (writeback or non-cached) by passing the pages to vmap() (see pfn_to_page() usage in persistent_ram_vmap() for more details) with specific flags. When read_kcore() starts iterating over the vmalloc region, it runs over the virtual address that vmap() returned for ramoops. In aligned_vread() the virtual address is passed to vmalloc_to_page() which returns the page struct for the reserved lowmem area. That lowmem page is passed to kmap_atomic(), which effectively calls page_to_virt() that assumes a lowmem page struct must be directly accessible with __va() and friends. These pages are mapped via vmap() though, and the lowmem mapping was never made, so accessing them via the lowmem virtual address oopses like above. Let's side-step this problem by passing VM_IOREMAP to vmap(). This will tell vread() to not include the ramoops region in the kcore. Instead the area will look like a bunch of zeros. The alternative is to teach kmap() about vmalloc areas that intersect with lowmem. Presumably such a change isn't a one-liner, and there isn't much interest in inspecting the ramoops region in kcore files anyway, so the most expedient route is taken for now. (CVE-2022-50849)

  - 已修复 Linux 内核中的下列漏洞：hwrng: amd - Fix PCI device refcount leak for_each_pci_dev() is implemented by pci_get_device(). The comment of pci_get_device() says that it will increase the reference count for the returned pci_dev and also decrease the reference count for the input pci_dev @from if it is not NULL. If we break for_each_pci_dev() loop with pdev not NULL, we need to call pci_dev_put() to decrease the reference count. Add the missing pci_dev_put() for the normal and error path. (CVE-2022-50868)

  - 已修复 Linux 内核中的下列漏洞：RDMA/srp: Do not call scsi_done() from srp_abort() After scmd_eh_abort_handler() has called the SCSI LLD eh_abort_handler callback, it performs one of the following actions: * Call scsi_queue_insert(). * Call scsi_finish_command(). * Call scsi_eh_scmd_add(). Hence, SCSI abort handlers must not call scsi_done(). Otherwise all the above actions would trigger a use-after-free. Hence remove the scsi_done() call from srp_abort(). Keep the srp_free_req() call before returning SUCCESS because we may not see the command again if SUCCESS is returned. (CVE-2023-52515)

    在 Linux 内核中发现多个可能导致权限升级、拒绝服务或信息泄漏的漏洞。

    对于 Debian 12 bookworm，这些问题已在版本 6.1.187-1中修复。

    建议您升级 linux 程序包。

    如需了解 linux 的详细安全状态，请参阅其安全跟踪页面：
    https://security-tracker.debian.org/tracker/linux

    有关 Debian LTS 安全公告、如何将这些更新应用到系统以及常见问题解答的更多信息，请访问以下网址：https://wiki.debian.org/LTS

Tenable 已直接从 Debian 安全公告中提取上述描述块。

请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。

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。

  - ALSA：usb-audio：system-resume 错误后的完全清理 系统恢复失败可使卡在重新启动之前无法使用。usb_audio_resume（） 在 snd_usb_pcm_resume（） 或 snd_usb_mixer_resume（） 失败时跳至err_out。错误路径会跳过 out： 区块，从而恢复 D0 并递减芯片>num_suspended_intf。该卡保持在 SNDRV_CTL_POWER_D3hot，因此稍后控制 snd_power_ref_and_wait（） 中的访问块。USB 核心记录接口恢复回调错误。它不会重试该回调，因此后续回调无法完成跳过的清除。usb_audio_suspend（） 在返回成功之前递增 num_suspended_intf。即使组件恢复失败，系统恢复回调也必须消耗系统暂停计数。否则，搁浅计数偏移稍后会暂停和恢复循环。不要将此清理应用于运行时恢复错误。运行时 PM 可在没有其他暂停回调的情况下重试 -EAGAIN 或 -EBUSY。计数必须继续描述该挂起的接口。其他运行时恢复错误runtime_error在 PM 核心中锁存，不会立即引起回调重试。system-resume 错误路径的这两个部分都存在很长时间。提交 88a8516a2128a（ALSA：usbaudio：实现 USB 自动暂停）err_out D0 还原后引入。提交 862b2509d157c（ALSA：usb-audio：修复恢复后不一致的卡 PM 状态）稍后将 num_suspended_intf-- 移动到 out： 区块。错误路径现在会跳过这两项操作。不需要第三方代码即可访问错误路径。
    snd_usb_mixer_resume（） 以 snd_usb_mixer_activate（） 结尾，其返回混合器状态为 URB 的设备的 usb_submit_urb（） 的结果。其混合器>private_resume钩子也可通过 scarlett2_init_notify（） 失败。snd_usb_pcm_resume（） 向 UAC3 power 域发出 SET_CUR 请求。当设备停止请求时，它可返回 -EPIPE 或 -EIO。仅当 system_suspend 为非零时，通过 out： 路由组件错误。继续通过err_out返回运行时恢复错误。后续的组件恢复阶段仍然会跳过。原始错误仍会到达 USB 核心。如果设备未恢复，以后的传输可能会失败。我再现了带有树外诊断混合器恢复钩子的 Audient iD14 MkI 上的系统恢复失败。在未修补的核心中注入的 -EIO 使控制读卡器在 snd_power_ref_and_wait（） 中处于不间断休眠状态，直到重新启动。通过此修补程序，相同故障可恢复控制访问权限。在禁用故障注入后，第二个系统暂停和恢复也会成功。（CVE-2026-80828）

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
