Linux Kernel squashfs double free denial of service

linux-squashfs-doublefree-dos (29967) The risk level is classified as LowLow Risk

Description:

The Linux Kernel is vulnerable to a denial of service caused by improper handling of corrupted filesystem structures by the squashfs module. A local attacker could exploit this vulnerability by executing a read operation on a corrupted squashfs image which would cause the kernel to free a buffer twice, resulting in a denial of service and possible data corruption.
