简介
AlmaLinux 主机缺少一个或多个安全更新。描述
AlmaLinux 9.6 主机上存在安装的程序包，该程序包受到 TuxCare ALMALINUX9.6：CLSA-2026：1778787063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：can: m_can: pci: add missing m_can_class_free_dev() in probe/remove methods In m_can_pci_remove() and error handling path of m_can_pci_probe(), m_can_class_free_dev() should be called to free resource allocated by m_can_class_allocate_dev(), otherwise there will be memleak. (CVE-2022-49024)
- 已修复 Linux 内核中的下列漏洞：ima: Fix a potential integer overflow in ima_appraise_measurement When the ima-modsig is enabled, the rc passed to evm_verifyxattr() may be negative, which may cause the integer overflow problem. (CVE-2022-49643)
- 已修复 Linux 内核中的下列漏洞：usbnet: fix memory leak in error case usbnet_write_cmd_async() mixed up which buffers need to be freed in which error case. v2: add Fixes tag v3: fix uninitialized buf pointer (CVE-2022-49657)
- 已修复 Linux 内核中的下列漏洞：can: j1939: j1939_send_one(): fix missing CAN header initialization The read access to struct canxl_frame::len inside of a j1939 created skbuff revealed a missing initialization of reserved and later filled elements in struct can_frame. This patch initializes the 8 byte CAN header with zero. (CVE-2022-49845)
- 已修复 Linux 内核中的下列漏洞：misc: tifm: fix possible memory leak in tifm_7xx1_switch_media() If device_register() returns error in tifm_7xx1_switch_media(), name of kobject which is allocated in dev_set_name() called in device_add() is leaked. Never directly free @dev after calling device_register(), even if it returned an error! Always use put_device() to give up the reference initialized. (CVE-2022-50349)
