RUSTSEC-2026-0244 `setlocale` and `TextDomain::init` are unsound as they access environment with no synchronization

setlocale and TextDomain::init are unsound and may allow safe code to exhibit undefined behavior when called in a multi-threaded program. The flaw is fixed in 0.8.0 by marking these functions unsafe and documenting the conditions under which they can be called safely...

PYSEC-2026-3358 Missing validation results in undefined behavior in `QuantizedConv2D`

Impact The implementation of tf.rawops.QuantizedConv2D does not fully validate the input arguments: python import tensorflow as tf input = tf.constant1, shape=1, 2, 3, 3, dtype=tf.quint8 filter = tf.constant1, shape=1, 2, 3, 3, dtype=tf.quint8 bad args mininput = tf.constant, shape=0,...

RUSTSEC-2026-0190 Unsoundness in `Error::downcast_mut()`

Affected versions of this crate violate borrow rules, resulting in undefined behavior, when the user adds context to an error via Error::context and then later calls Error::downcastmut on the returned Error. The flaw was corrected in commit 6e8c000 by revising how the mutable reference is...

CVE-2026-40279 BACnet Stack: Undefined-behavior signed left shift in `decode_signed32()`

BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to 1.4.3, decodesigned32 in src/bacnet/bacint.c reconstructs a 32-bit signed integer from four APDU bytes using signed left shifts. When any of the four bytes has bit 7 set value ≥ 0x80, the left-shift...
