Util-linux: util-linux: heap use-after-free in libblkid nested partition probing
Vulnerability Description
A flaw was found in the libblkid library of util-linux. During nested partition probing, the BSD, Minix, Solaris x86, and UnixWare partition probers cache a raw pointer to a parent partition entry in a dynamically allocated array. When subsequent partition additions cause the array to be reallocated, this pointer becomes stale, leading to a heap use-after-free read. An attacker who can present a crafted block device image (for example, via USB insertion or a loop-mounted disk image) can trigger this flaw without user interaction, as libblkid is invoked automatically by udev/udisks as root on block-device hot-plug events. This could lead to limited information disclosure or denial of service.

util-linux 资源管理错误漏洞
Vulnerability Description
util-linux是util-linux组织开源的一个软件包。 util-linux存在资源管理错误漏洞,该漏洞源于在嵌套分区探测过程中,BSD、Minix、Solaris x86和UnixWare分区探测程序在动态分配的数组中缓存指向父分区条目的原始指针,当后续分区添加导致数组重新分配时,该指针失效,导致堆释放后重用读取。攻击者可以通过呈现特制块设备映像(如通过USB插入或循环挂载的磁盘映像)触发此漏洞,可能导致有限的信息泄露或拒绝服务。以下版本受到影响:Red Hat Enterprise Linu
