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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
11889 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2025-05-01 15:31 – Updated: 2025-05-07 15:31In the Linux kernel, the following vulnerability has been resolved:
bpf, test_run: Fix alignment problem in bpf_prog_test_run_skb()
We got a syzkaller problem because of aarch64 alignment fault if KFENCE enabled. When the size from user bpf program is an odd number, like 399, 407, etc, it will cause the struct skb_shared_info's unaligned access. As seen below:
