CWE-416
AllowedUse After Free
Abstraction: Variant · Status: Stable
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
9821 vulnerabilities reference this CWE, most recent first.

EHCI does not verify if the Buffer Pointer overlaps with its MMIO region when it transfers the USB packets. Crafted content may be written to the controller's registers and trigger undesirable actions (such as reset) while the device is still transferring packets. This can ultimately lead to a use-after-free issue. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition, or potentially execute arbitrary code within the context of the QEMU process on the host.

GHSA-2V78-H87M-HPX9
Vulnerability from github – Published: 2025-07-25 15:30 – Updated: 2025-12-18 18:30In the Linux kernel, the following vulnerability has been resolved:
rose: fix dangling neighbour pointers in rose_rt_device_down()
There are two bugs in rose_rt_device_down() that can cause use-after-free:
-
The loop bound
t->countis modified within the loop, which can cause the loop to terminate early and miss some entries. -
When removing an entry from the neighbour array, the subsequent entries are moved up to fill the gap, but the loop index
iis still incremented, causing the next entry to be skipped.
For example, if a node has three neighbours (A, A, B) with count=3 and A is being removed, the second A is not checked.
i=0: (A, A, B) -> (A, B) with count=2
^ checked
i=1: (A, B) -> (A, B) with count=2
^ checked (B, not A!)
i=2: (doesn't occur because i < count is false)
This leaves the second A in the array with count=2, but the rose_neigh
structure has been freed. Code that accesses these entries assumes that
the first count entries are valid pointers, causing a use-after-free
when it accesses the dangling pointer.
Fix both issues by iterating over the array in reverse order with a fixed loop bound. This ensures that all entries are examined and that the removal of an entry doesn't affect subsequent iterations.

Mitigation
Strategy: Language Selection
Choose a language that provides automatic memory management.
Mitigation
Strategy: Attack Surface Reduction
When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
