CVE-2026-27171

zlib before 1.3.2 allows CPU consumption via crc32combine64 and crc32combinegen64 because x2nmodp can do right shifts within a loop that has no termination condition...

CVE-2026-27171

CVE-2026-27171 affects zlib versions before 1.3.2. The issue arises from crc32_combine64/crc32_combine_gen64 where a loop in x2nmodp can run with no termination condition, causing an infinite loop and excessive CPU usage (DoS). Multiple connected advisories confirm the DoS impact and the fix in z...

Linux Distros Unpatched Vulnerability : CVE-2026-27171

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - zlib before 1.3.2 allows CPU consumption via crc32combine64 and crc32combinegen64 because x2nmodp can do right shifts within a loop that has no termination...

zlib 安全漏洞

Zlib is a general-purpose data compression library developed by Mark Adler in the United States. Versions of Zlib prior to 1.3.2 contained security vulnerabilities. These vulnerabilities stemmed from the x2nmodp function in the crc32combine64 and crc32combinegen64 functions, which allowed right...

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...
