FreeBSD : Python -- use-after-free vulnerability in decompressors under memory pressure (b8e9f33c-375d-11f1-a119-e36228bfe7d4)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the b8e9f33c-375d-11f1-a119-e36228bfe7d4 advisory. Seth Larson reports: There is a CRITICAL severity vulnerability affecting CPython. Use-after-free UAF w...

Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-007368)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-007368 advisory. In the Linux kernel, the following vulnerability has been resolved: igb: Do not free qvector unless new one was allocated Avoid potential use-after-free condition...

EUVD-2026-22028

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...
