CVE-2026-93216

A flaw was found in the Linux kernel. A Time-of-check to time-of-use TOCTOU vulnerability exists in the printpageownermemcg function, where page-memcgdata is read multiple times without proper locking. If a memory page is concurrently freed and reallocated between these reads, it can trigger...
