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...

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...
