cryptography: Cryptography: Buffer overflow via non-contiguous buffer in API

A flaw was found in the cryptography library. This vulnerability occurs when a non-contiguous buffer is passed to certain application programming interfaces APIs that accept Python buffers, such as Hash.update. A remote attacker could exploit this to cause a buffer overflow, potentially leading t...

CVE-2026-43149

In the Linux kernel, the following vulnerability has been resolved: net: wan/fslucchdlc: Fix dmafreecoherent in uhdlcmemclean The priv-rxbuffer and priv-txbuffer are alloc'd together as contiguous buffers in uhdlcinit but freed as two buffers in uhdlcmemclean. Change the cleanup to only call...

CVE-2026-39892

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. From 45.0.0 to before 46.0.7, if a non-contiguous buffer was passed to APIs which accepted Python buffers e.g. Hash.update, this could lead to buffer overflows. This vulnerability is fixed in...
