简介
CentOS Linux 主机缺少一个或多个安全更新。描述
CentOS Linux 8 主机上存在安装的程序包，该程序包受到 TuxCare CENTOS-STREAM8：CLSA-2025：1738592614 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：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)
- 已修复 Linux 内核中的下列漏洞：smb: client: fix potential UAF in cifs_debug_files_proc_show() Skip sessions that are being teared down (status == SES_EXITING) to avoid UAF. (CVE-2024-26928)
- 已修复 Linux 内核中的下列漏洞：smb: client: fix potential UAF in cifs_signal_cifsd_for_reconnect() Skip sessions that are being teared down (status == SES_EXITING) to avoid UAF. (CVE-2024-35861)
- 已修复 Linux 内核中的下列漏洞：smb: client: fix potential UAF in is_valid_oplock_break() Skip sessions that are being teared down (status == SES_EXITING) to avoid UAF.
(CVE-2024-35863)
- 已修复 Linux 内核中的下列漏洞：smb: client: fix potential UAF in smb2_is_valid_lease_break() Skip sessions that are being teared down (status == SES_EXITING) to avoid UAF.
(CVE-2024-35864)
