概要
CentOS Linux 主機缺少一個或多個安全性更新。說明
CentOS Linux 7 主機已安裝的套件受到 TuxCare CENTOS7：CLSA-2025：1738672047 公告中提及的多個弱點影響。- 在 Linux 核心中發現一個歸類爲「嚴重」的弱點。此弱點會影響 Bluetooth 元件中 net/bluetooth/l2cap_core.c 檔案的 l2cap_conn_del 函式。操控此弱點可導致釋放後使用。建議套用修補程式以修正此問題。此弱點的相關識別碼是 VDB-211944。(CVE-2022-3640)
- 已解決 Linux 核心中的下列弱點：ceph: prevent use-after-free in encode_cap_msg() In fs/ceph/caps.c, in encode_cap_msg(), use after free error was caught by KASAN at this line - 'ceph_buffer_get(arg->xattr_buf);'. This implies before the refcount could be increment here, it was freed. In same file, in handle_cap_grant() refcount is decremented by this line - 'ceph_buffer_put(ci->i_xattrs.blob);'. It appears that a race occurred and resource was freed by the latter line before the former line could increment it. encode_cap_msg() is called by __send_cap() and
__send_cap() is called by ceph_check_caps() after calling __prep_cap(). __prep_cap() is where arg->xattr_buf is assigned to ci->i_xattrs.blob. This is the spot where the refcount must be increased to prevent use after free error. (CVE-2024-26689)
- 已解決 Linux 核心中的下列弱點：drm/amdgpu: add missing size check in amdgpu_debugfs_gprwave_read() Avoid a possible buffer overflow if size is larger than 4K. (cherry picked from commit f5d873f5825b40d886d03bd2aede91d4cf002434) (CVE-2024-50282)
- 已解決 Linux 核心中的下列弱點：hv_sock: Initializing vsk->trans to NULL to prevent a dangling pointer When hvs is released, there is a possibility that vsk->trans may not be initialized to NULL, which could lead to a dangling pointer. This issue is resolved by initializing vsk->trans to NULL. (CVE-2024-53103)
- 已解決 Linux 核心中的下列弱點：netfilter: ipset: add missing range check in bitmap_ip_uadt When tb[IPSET_ATTR_IP_TO] is not present but tb[IPSET_ATTR_CIDR] exists, the values of ip and ip_to are slightly swapped. Therefore, the range check for ip should be done later, but this part is missing and it seems that the vulnerability occurs. So we should add missing range checks and remove unnecessary range checks. (CVE-2024-53141)
