Weakness (CWE)
CWE-908: Use of Uninitialized Resource
The product uses or accesses a resource that has not been initialized.
How to prevent it (4 mitigations)
-
Implementation
Explicitly initialize the resource before use. If this is performed through an API function or standard procedure, follow all required steps.
-
Implementation
Pay close attention to complex conditionals that affect initialization, since some branches might not perform the initialization.
-
Implementation
Avoid race conditions (CWE-362) during initialization routines.
-
Build and Compilation
Run or compile the product with settings that generate warnings about uninitialized variables or data.

UpdateHub probe: uninitialized-heap out-of-bounds read of network-supplied metadata
The UpdateHub OTA client in subsys/mgmt/updatehub/updatehub.c contains an out-of-bounds / uninitialized-memory read in z_impl_updatehub_probe(). The probe response from the UpdateHub server is copied into a heap buffer (metadata) that is correctly NUL-termina…

Sssd: sssd: nss responder uninitialized heap disclosure in initgroups reply
A flaw was found in SSSD. The sss_nss_protocol_fill_initgr() function in the NSS responder pre-allocates reply space for all group entries but does not shrink the packet when groups are skipped, causing uninitialized heap bytes to be transmitted to the client…

libjxl: Uninitialized memory read in decoder due to incorrect optimization in patch handling
A specially-crafted file can cause libjxl's decoder to read pixel data from uninitialized (but allocated) memory. This can be done by causing the decoder to reference an outside-image-bound area in a subsequent patches. An incorrect optimization causes the de…

Direct Ring Buffer has uninitialized memory exposure in create_ring_buffer
The safe function `create_ring_buffer` allocates a buffer using `Vec::with_capacity` followed by `set_len`, creating a `Box<[T]>` containing uninitialized memory. This leads to undefined behavior when functions like `write_slices` create typed slices (e.g., `…

static-alloc vulnerability leads to uninitialized read after allocating MemBump
The affected function, `MemBump::new()`, would allocate memory without initializing it. Subsequently calling the created value's various `alloc`methods would then read and write the start of that memory as a `Cell` which isundefined behavior. Instead, it shou…
