Linux · Linux Kernel · CVE-2025-21671
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
The issue is related to a potential use-after-free (UAF) in the zram table. If `zram meta alloc` fails early, it frees the allocated `zram->table` without setting it to NULL, which can cause `zram meta free` to access the table if a user resets a failed and uninitialized device. This could potentially impact the confidentiality, integrity, and availability of protected information.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
