CVE-2026-89991

CVE-2026-89991 is a bug in the Linux kernel BPF subsystem affecting __pcpu_freelist_push(). When only one CPU is possible (e.g., CONFIG_SMP=n or nr_cpus=1), an NMI re-enters pcpu_freelist_push() while the interrupted context already holds that CPU's freelist lock. The fallback loop skips the curr...

CVE-2026-89987

CVE-2026-89987 affects the Linux kernel in the mm/huge_memory subsystem. The function zap_huge_pmd_folio() fails to propagate the PMD dirty bit to the folio when a PMD-mapped shmem/tmpfs page is unmapped, unlike the PTE path and PMD split path. This causes silent data loss for processes that stor...
