UBUNTU-CVE-2025-39941

In the Linux kernel, the following vulnerability has been resolved: zram: fix slot write race condition Parallel concurrent writes to the same zram index result in leaked zsmalloc handles. Schematically we can have something like this: CPU0 CPU1 zramslotlock zsfreehandle zramslotlock zramslotlock...

CVE-2025-39941

CVE-2025-39941 describes a race in zram slot handling in the Linux kernel. Parallel writes to the same zram index can leak zsmalloc handles because zs_free() may run too early; the fix requires resetting the zram entry right before assigning a new handle within the same slot lock scope. Documents...
