Descripción técnica

A use-after-free vulnerability in the pybddisasm Python bindings affects structure-valued members of INSTRUX objects. These members are exposed through Python objects that reference memory owned by the parent INSTRUX object. A retained reference to a member does not keep the parent allocation alive. Accessing the member after the parent INSTRUX object has been freed therefore accesses freed memory. Depending on how the member is used and whether the freed allocation has been reused, this may expose process memory or cause the Python process to crash. Exploitation requires an application to retain and subsequently access a member reference after the parent object has been freed. The pybddisasm package is no longer maintained.

CVE-2026-118446—

——0A use-after-free vulnerability in the pybddisasm Python bindings affects array-valued members of INSTRUX objects, including ND_OPERAND arrays. These arrays are exposed as Python lists whose elements reference memory owned by the parent INSTRUX object. Retaining a list or an element does not keep the parent allocation alive. Accessing an element after the parent INSTRUX object has been freed therefore accesses freed memory. Depending on how the element is used and whether the freed allocation has been reused, this may expose process memory or cause the Python process to crash. Exploitation requires an application to retain and subsequently access an array element after the parent object has been freed. The pybddisasm package is no longer maintained.4h CVE-2026-113421—

——0In Eclipse ThreadX versions 6.0.1 through 6.5.2.202603, ThreadX Modules does not revoke a module's trace-buffer-full callback when the module is stopped and unloaded. With event tracing enabled and a kernel-owned trace buffer still active, a later buffer wrap invokes the callback from privileged thread context after the module's code has been released, so a user-mode module can have its code run with kernel privileges after unload, or, once the memory is reused, redirect control flow or cause a fault.4h CVE-2026-590448.4 ALT

——0In multiple locations, there is a possible use-after-free due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.8h CVE-2026-589848.4 ALT

——0In do_fault_around of memory.c, there is a possible use after free due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.8h CVE-2026-588298.4 ALT
