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...
