CVE-2026-23157

CVE-2026-23157 is a Linux kernel vulnerability affecting the btrfs metadata writeback path. The issue occurs in the balance between dirty pages and a cgroup/global dirty limit, where an internal 32 MiB threshold for btrfs btree inode writeback prevents progress when the cgroup’s dirty pages excee...

CVE-2026-23147

The CVE-2026-23147 issue concerns Linux kernel btrfs zlib compression on S390 hardware acceleration. After a refactor (S390x HW acceleration), the code stopped releasing the page cache folio returned by btrfs_compress_filemap_get_folio(), leading to a folio leak. The root cause is a missing folio...
