CVE-2026-23025

CVE-2026-23025 : In the Linux kernel, drain_page_zone() could corrupt per-CPU pages (pcp) when an interrupt occurs and code path uses spin_lock(&pcp->lock) with SMP=n, because spin_trylock() may fail. The issue enables potential pcp structure corruption. The fix adds local wrappers that conver...
