Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - 已解決 Linux 核心中的下列弱點：drm/amd/display: Fix potential null dereference The adev->dm.dc pointer can be NULL and dereferenced in amdgpu_dm_fini() without checking. Add a NULL pointer check before calling dc_dmub_srv_destroy(). Found by Linux Verification Center (linuxtesting.org) with SVACE. (CVE-2023-53498)

請注意，Nessus 依賴供應商報告的套件存在。

AlmaLinux 9.2 主機已安裝的套件會受到 TuxCare ALMALINUX9.2：CLSA-2026：1777616064 公告中提及的多個弱點影響。

  - 已解決 Linux 核心中的下列弱點：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)

  - 已解決 Linux 核心中的下列弱點：net: mdio: fix undefined behavior in bit shift for __mdiobus_register Shifting signed 32-bit value by 31 bits is undefined, so changing significant bit to unsigned. The UBSAN warning calltrace like below: UBSAN: shift-out-of-bounds in drivers/net/phy/mdio_bus.c:586:27 left shift of 1 by 31 places cannot be represented in type 'int' Call Trace: <TASK> dump_stack_lvl+0x7d/0xa5 dump_stack+0x15/0x1b ubsan_epilogue+0xe/0x4e

  - 已解決 Linux 核心中的下列弱點：vt: Clear selection before changing the font When changing the console font with ioctl(KDFONTOP) the new font size can be bigger than the previous font. A previous selection may thus now be outside of the new screen size and thus trigger out-of-bounds accesses to graphics memory if the selection is removed in vc_do_resize(). Prevent such out-of-memory accesses by dropping the selection before the various con_font_set() console handlers are called.
    (CVE-2022-49948)

  - 已解決 Linux 核心中的下列弱點：wifi: iwlwifi: mvm: fix double free on tx path. We see kernel crashes and lockups and KASAN errors related to ax210 firmware crashes. One of the KASAN dumps pointed at the tx path, and it appears there is indeed a way to double-free an skb. If iwl_mvm_tx_skb_sta returns non-zero, then the 'skb' sent into the method will be freed. But, in case where we build TSO skb buffer, the skb may also be freed in error case. So, return 0 in that particular error case and do cleanup manually.

  - 已解決 Linux 核心中的下列弱點：mmc: rtsx_usb_sdmmc: fix return value check of mmc_add_host() mmc_add_host() may return error, if we ignore its return value, the memory that allocated in mmc_alloc_host() will be leaked and it will lead a kernel crash because of deleting not added device in the remove path. So fix this by checking the return value and calling mmc_free_host() in the error path, besides, led_classdev_unregister() and pm_runtime_disable() also need be called.
