CVE-2025-39941
CVE-2025-39941 relates to the Linux kernel zram subsystem. The vulnerability arises from a race in slot write handling where parallel writes to the same zram index can leak zsmalloc handles because zs_free() is executed too early. The documented fix is to reset the zram entry and assign the new h...
