  - Linux 内核 5.12.14 中的 kernel/module.c 未正确处理签名验证，又称为 CID-0c18f29aae7c。如果没有CONFIG_MODULE_SIG，则不会针对 module.sig_enforce=1 命令行参数验证内核模块已签名以通过init_module加载。（CVE-2021-35039）

  - 在 5.13.4 之前的 Linux 内核的 drivers/char/virtio_console.c 中，不受信任的设备提供超过缓冲区大小的 buf->len 值时可以触发数据损坏或丢失。注意：供应商表示，所述数据损坏在任何现有使用案例中都不属于漏洞；添加长度验证只是为了在面对主机 OS 异常行为时保持稳定 (CVE-2021-38160)

  - 已修复 Linux 内核中的下列漏洞：tracing: Fix potential double free in create_var_ref() In create_var_ref(), init_var_ref() is called to initialize the fields of variable ref_field, which is allocated in the previous function call to create_hist_field(). Function init_var_ref() allocates the corresponding fields such as ref_field->system, but frees these fields when the function encounters an error. The caller later calls destroy_hist_field() to conduct error handling, which frees the fields and the variable itself. This results in double free of the fields which are already freed in the previous function. Fix this by storing NULL to the corresponding fields when they are freed in init_var_ref(). (CVE-2022-49410)

AlmaLinux 9.2 主机上存在安装的程序包，该程序包受到 TuxCare ALMALINUX9.2：CLSA-2025：1738671431公告中提及的多个漏洞的影响。

  - 已修复 Linux 内核中的下列漏洞：memcg: fix possible use-after-free in memcg_write_event_control() memcg_write_event_control() accesses the dentry->d_name of the specified control fd to route the write call. As a cgroup interface file can't be renamed, it's safe to access d_name as long as the specified file is a regular cgroup file. Also, as these cgroup interface files can't be removed before the directory, it's safe to access the parent too. Prior to 347c4a874710 (memcg: remove cgroup_event->cft), there was a call to __file_cft() which verified that the specified file is a regular cgroupfs file before further accesses. The cftype pointer returned from __file_cft() was no longer necessary and the commit inadvertently dropped the file type check with it allowing any file to slip through. With the invarients broken, the d_name and parent accesses can now race against renames and removals of arbitrary files and cause use-after-free's. Fix the bug by resurrecting the file type check in
    __file_cft(). Now that cgroupfs is implemented through kernfs, checking the file operations needs to go through a layer of indirection. Instead, let's check the superblock and dentry type. (CVE-2022-48988)

  - 已修复 Linux 内核中的下列漏洞：x86/alternatives: Disable KASAN in apply_alternatives() Fei has reported that KASAN triggers during apply_alternatives() on a 5-level paging machine: BUG: KASAN: out-of-bounds in rcu_is_watching() Read of size 4 at addr ff110003ee6419a0 by task swapper/0/0 ... __asan_load4() rcu_is_watching() trace_hardirqs_on() text_poke_early() apply_alternatives() ... On machines with 5-level paging, cpu_feature_enabled(X86_FEATURE_LA57) gets patched. It includes KASAN code, where KASAN_SHADOW_START depends on __VIRTUAL_MASK_SHIFT, which is defined with cpu_feature_enabled(). KASAN gets confused when apply_alternatives() patches the KASAN_SHADOW_START users. A test patch that makes KASAN_SHADOW_START static, by replacing
    __VIRTUAL_MASK_SHIFT with 56, works around the issue. Fix it for real by disabling KASAN while the kernel is patching alternatives. [ mingo: updated the changelog ] (CVE-2023-52504)

  - 已修复 Linux 内核中的下列漏洞：HID: intel-ish-hid: ipc: Disable and reenable ACPI GPE bit The EHL (Elkhart Lake) based platforms provide a OOB (Out of band) service, which allows to wakup device when the system is in S5 (Soft-Off state). This OOB service can be enabled/disabled from BIOS settings. When enabled, the ISH device gets PME wake capability. To enable PME wakeup, driver also needs to enable ACPI GPE bit. On resume, BIOS will clear the wakeup bit. So driver need to re-enable it in resume function to keep the next wakeup capability. But this BIOS clearing of wakeup bit doesn't decrement internal OS GPE reference count, so this reenabling on every resume will cause reference count to overflow. So first disable and reenable ACPI GPE bit using acpi_disable_gpe(). (CVE-2023-52519)

  - 已修复 Linux 内核中的下列漏洞：wifi: iwlwifi: mvm: Fix a memory corruption issue A few lines above, space is kzalloc()'ed for: sizeof(struct iwl_nvm_data) + sizeof(struct ieee80211_channel) + sizeof(struct ieee80211_rate) 'mvm->nvm_data' is a 'struct iwl_nvm_data', so it is fine. At the end of this structure, there is the 'channels' flex array. Each element is of type 'struct ieee80211_channel'. So only 1 element is allocated in this array. When doing:
    mvm->nvm_data->bands[0].channels = mvm->nvm_data->channels; We point at the first element of the 'channels' flex array. So this is fine. However, when doing: mvm->nvm_data->bands[0].bitrates = (void
    *)((u8 *)mvm->nvm_data->channels + 1); because of the (u8 *) cast, we add only 1 to the address of the beginning of the flex array. It is likely that we want point at the 'struct ieee80211_rate' allocated just after. Remove the spurious casting so that the pointer arithmetic works as expected. (CVE-2023-52531)
