英文标题:
Grub2: missing unregister call for normal commands may lead to use-after-free
漏洞描述
中文描述:
GNU GRUB是GNU社区的一款Linux系统引导程序。 GNU GRUB存在安全漏洞，该漏洞源于normal命令释放后重用，可能导致拒绝服务或系统崩溃。
英文描述:
A vulnerability has been identified in the GRUB2 bootloader's normal command that poses an immediate Denial of Service (DoS) risk. This flaw is a Use-after-Free issue, caused because the normal command is not properly unregistered when the module is unloaded. An attacker who can execute this command can force the system to access memory locations that are no longer valid. Successful exploitation leads directly to system instability, which can result in a complete crash and halt system availability. Impact on the data integrity and confidentiality is also not discarded.
