Memory corruption due to concurrent user-mode buffer modification

IdentifiersCVE-2026-25260CWE-367· Time-of-check Time-of-use (TOCTOU)…

CVE-2026-25260 is a memory corruption vulnerability caused by accessing shared buffers without validating whether user-mode input has been concurrently modified. The available description indicates a race-condition style flaw in which a component operates on shared memory or buffers originating from user mode while failing to ensure the data remains stable between validation and use. This can result in memory corruption during processing of the affected buffer.
