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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
9816 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2025-09-18 15:30 – Updated: 2025-12-12 18:30In the Linux kernel, the following vulnerability has been resolved:
cifs: prevent use-after-free by freeing the cfile later
In smb2_compound_op we have a possible use-after-free which can cause hard to debug problems later on.
This was revealed during stress testing with KASAN enabled kernel. Fixing it by moving the cfile free call to a few lines below, after the usage.

GHSA-2H3Q-MH3Q-C4FJ
Vulnerability from github – Published: 2026-05-27 15:33 – Updated: 2026-06-25 21:31In the Linux kernel, the following vulnerability has been resolved:
power: supply: pm8916_bms_vm: Fix use-after-free in power_supply_changed()
Using the devm_ variant for requesting IRQ before the devm_
variant for allocating/registering the power_supply handle, means that
the power_supply handle will be deallocated/unregistered before the
interrupt handler (since devm_ naturally deallocates in reverse
allocation order). This means that during removal, there is a race
condition where an interrupt can fire just after the power_supply
handle has been freed, but just before the corresponding
unregistration of the IRQ handler has run.
This will lead to the IRQ handler calling power_supply_changed() with
a freed power_supply handle. Which usually crashes the system or
otherwise silently corrupts the memory...
Note that there is a similar situation which can also happen during
probe(); the possibility of an interrupt firing before registering
the power_supply handle. This would then lead to the nasty situation
of using the power_supply handle uninitialized in
power_supply_changed().
Fix this racy use-after-free by making sure the IRQ is requested after
the registration of the power_supply handle.

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.
No CAPEC attack patterns related to this CWE.
