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)

  - 已解決 Linux 核心中的下列弱點：mtd: Fix device name leak when register device failed in add_mtd_device() There is a kmemleak when register device failed: unreferenced object 0xffff888101aab550 (size 8): comm insmod, pid 3922, jiffies 4295277753 (age 925.408s) hex dump (first 8 bytes): 6d 74 64 30 00 88 ff ff mtd0.... backtrace: [<00000000bde26724>]

(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)
