CentOS Linux 6 主機安裝的套件會受到 TuxCare CENTOS6：CLSA-2026：1792245431 公告中提及的多個弱點影響。

  - 已解決 Linux 核心中的下列弱點：virtio_console: eliminate anonymous module_init & module_exit Eliminate anonymous module_init() and module_exit(), which can lead to confusion or ambiguity when reading System.map, crashes/oops/bugs, or an initcall_debug log. Give each of these init and exit functions unique driver-specific names to eliminate the anonymous names. Example 1: (System.map) ffffffff832fc78c t init ffffffff832fc79e t init ffffffff832fc8f8 t init Example 2: (initcall_debug log) calling init+0x0/0x12 @ 1 initcall init+0x0/0x12 returned 0 after 15 usecs calling init+0x0/0x60 @ 1 initcall init+0x0/0x60 returned 0 after 2 usecs calling init+0x0/0x9a @ 1 initcall init+0x0/0x9a returned 0 after 74 usecs (CVE-2022-49100)

(CVE-2022-50566)

  - 已解決 Linux 核心中的下列弱點：media: dvb-frontends: fix leak of memory fw (CVE-2022-50664)

  - 已解決 Linux 核心中的下列弱點：acct: fix potential integer overflow in encode_comp_t() The integer overflow is descripted with following codes: > 317 static comp_t encode_comp_t(u64 value) > 318 { > 319 int exp, rnd; ...... > 341 exp <<= MANTSIZE; > 342 exp += value; > 343 return exp; > 344 } Currently comp_t is defined as type of '__u16', but the variable 'exp' is type of 'int', so overflow would happen when variable 'exp' in line 343 is greater than 65535. (CVE-2022-50749)

  - 已解決 Linux 核心中的下列弱點：ext2: Add sanity checks for group and filesystem size Add sanity check that filesystem size does not exceed the underlying device size and that group size is big enough so that metadata can fit into it. This avoid trying to mount some crafted filesystems with extremely large group counts. (CVE-2022-50815)

CentOS Linux 7 主機已安裝的套件會受到 TuxCare CENTOS7：CLSA-2026：1792751247 公告中提及的多個弱點影響。

  - 已解決 Linux 核心中的下列弱點：mmmremap.c: avoid pointless invalidate_range_start/end on mremap(old_size=0) If an mremap() syscall with old_size=0 ends up in move_page_tables(), it will call invalidate_range_start()/invalidate_range_end() unnecessarily, i.e. with an empty range. This causes a WARN in KVM's mmu_notifier. In the past, empty ranges have been diagnosed to be off-by-one bugs, hence the WARNing. Given the low (so far) number of unique reports, the benefits of detecting more buggy callers seem to outweigh the cost of having to fix cases such as this one, where userspace is doing something silly. In this particular case, an early return from move_page_tables() is enough to fix the issue. (CVE-2022-49077)

  - 已解決 Linux 核心中的下列弱點：virtio_console: eliminate anonymous module_init & module_exit Eliminate anonymous module_init() and module_exit(), which can lead to confusion or ambiguity when reading System.map, crashes/oops/bugs, or an initcall_debug log.

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

  - mfd：sm501：修正移除期間潛在的記憶體洩漏 對應的移除函式 sm501_pci_remove（） 和 sm501_plat_remove（） 未釋放配置給 sm501_pci_probe（） 和 sm501_plat_probe（） 中結構sm501_devdata的記憶體。透過新增對 kfree（） 的呼叫來解決此問題。（CVE-2026-80974）

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。
