  "details" : [ "A vulnerability was identified in the Linux kernel's ext4 filesystem implementation due to a flaw in how it processes filesystem metadata. An attacker with local privileges could create a malicious ext4 filesystem image to trigger this issue. When the system attempts to mount this malicious image, the kernel performs an incorrect calculation. This action results in unpredictable system behavior." ],
