CVE-2026-6100

CVE-2026-6100 affects Python’s decompression modules: at least the in-process reuse of decompressor instances in lzma.LZMADecompressor , bz2.BZ2Decompressor , and gzip.GzipFile can lead to a Use-After-Free (UAF) if a memory allocation fails with a MemoryError and the decompressor is reused. The i...

Expired Pointer Dereference

Overview Affected versions of this package are vulnerable to Expired Pointer Dereference in the lzma.LZMADecompressor, bz2.BZ2Decompressor, and gzip.GzipFile modules. An attacker can execute arbitrary code or access sensitive information by triggering a use-after-free condition through repeated...

CVE-2026-6100

Use-after-free UAF was possible in the lzma.LZMADecompressor, bz2.BZ2Decompressor, and gzip.GzipFile when a memory allocation fails with a MemoryError and the decompression instance is re-used. This scenario can be triggered if the process is under memory pressure. The fix cleans up the dangling...
