Linux Distros Unpatched Vulnerability : CVE-2026-23147

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - btrfs: zlib: fix the folio leak on S390 hardware acceleration BUG After commit aa60fe12b4f4 btrfs: zlib: refactor S390x HW acceleration buffer preparation, we n...

CVE-2026-23147

A memory leak flaw was found in the Linux kernel's btrfs filesystem zlib compression code when using S390 hardware acceleration. Due to a missing folioput call in the copydataintobuffer function, page cache folios are not released after use during compression operations. This can lead to gradual...

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...
