Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a loop device not exclusively updating the block size...

SUSE CVE-2025-8067

A flaw was found in the Udisks daemon, where it allows unprivileged users to create loop devices using the D-BUS system. This is achieved via the loop device handler, which handles requests sent through the D-BUS interface. As two of the parameters of this handle, it receives the file descriptor...

USN-7723-1 udisks2 vulnerability

Michael Imfeld discovered that UDisks did not check the validity of input data correctly when handling files for loop devices. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code...

CVE-2025-8067

Summary: CVE-2025-8067 is an out-of-bounds read in the UDisks2 daemon via the D-Bus loop device handler, where a negative index is not validated. This can allow unprivileged users to crash the daemon or perform local privilege escalation by accessing files owned by privileged users. What’s affect...

CVE-2025-38620

The CVE-2025-38620 vulnerability affects the Linux kernel’s zloop (zoned loop) device. It arises from a use-after-free in blk_mq_free_tag_set() during zloop removal: zloop_ctl_remove() frees zlo memory (via zloop_free_disk()) and then accesses zlo->tag_set, which now points to freed memory. Th...
