概要
AlmaLinux 主機缺少一個或多個安全性更新。說明
AlmaLinux 9.2 主機已安裝的套件會受到 TuxCare ALMALINUX9.2：CLSA-2026：1787935638 公告中提及的多個弱點影響。- 已解決 Linux 核心中的下列弱點：fs/mount_setattr: always cleanup mount_kattr Make sure that finish_mount_kattr() is called after mount_kattr was succesfully built in both the success and failure case to prevent leaking any references we took when we built it. We returned early if path lookup failed thereby risking to leak an additional reference we took when building mount_kattr when an idmapped mount was requested. (CVE-2021-46923)
- 已解決 Linux 核心中的下列弱點：vdpa: ifcvf: Do proper cleanup if IFCVF init fails ifcvf_mgmt_dev leaks memory if it is not freed before returning. Call is made to correct return statement so memory does not leak. ifcvf_init_hw does not take care of this so it is needed to do it here. (CVE-2022-48706)
- 已解決 Linux 核心中的下列弱點：tracing/histogram: Fix a potential memory leak for kstrdup() kfree() is missing on an error path to free the memory allocated by kstrdup(): p = param = kstrdup(data->params[i], GFP_KERNEL); So it is better to free it via kfree(p). (CVE-2022-48768)
- 已解決 Linux 核心中的下列弱點：efi: fix NULL-deref in init error path In cases where runtime services are not supported or have been disabled, the runtime services workqueue will never have been allocated. Do not try to destroy the workqueue unconditionally in the unlikely event that EFI initialisation fails to avoid dereferencing a NULL pointer. (CVE-2022-48879)
- 已解決 Linux 核心中的下列弱點：can: af_can: fix NULL pointer dereference in can_rcv_filter Analogue to commit 8aa59e355949 (can: af_can: fix NULL pointer dereference in can_rx_register()) we need to check for a missing initialization of ml_priv in the receive path of CAN frames. Since commit 4e096a18867a (net: introduce CAN specific pointer in the struct net_device) the check for dev->type to be ARPHRD_CAN is not sufficient anymore since bonding or tun netdevices claim to be CAN devices but do not initialize ml_priv accordingly. (CVE-2022-48977)
