Common Weakness Enumeration

CWE-416

Allowed

Use After Free

Abstraction: Variant · Status: Stable

API response cwe.mitre.org

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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.

Vulnerability from github – Published: 2024-08-26 12:31 – Updated: 2024-09-12 21:32

Details

In the Linux kernel, the following vulnerability has been resolved:

f2fs: fix to cover read extent cache access with lock

syzbot reports a f2fs bug as below:

BUG: KASAN: slab-use-after-free in sanity_check_extent_cache+0x370/0x410 fs/f2fs/extent_cache.c:46 Read of size 4 at addr ffff8880739ab220 by task syz-executor200/5097

We missed to cover sanity_check_extent_cache() w/ extent cache lock, so, below race case may happen, result in use after free issue.

  • f2fs_iget
  • do_read_inode
  • f2fs_init_read_extent_tree : add largest extent entry in to cache - shrink - f2fs_shrink_read_extent_tree - __shrink_extent_tree - __detach_extent_node : drop largest extent entry
  • sanity_check_extent_cache : access et->largest w/o lock

let's refactor sanity_check_extent_cache() to avoid extent cache access and call it before f2fs_init_read_extent_tree() to fix this issue.

Vulnerability from github – Published: 2025-10-04 18:31 – Updated: 2026-02-06 15:30
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

clk: imx: scu: use _safe list iterator to avoid a use after free

This loop is freeing "clk" so it needs to use list_for_each_entry_safe(). Otherwise it dereferences a freed variable to get the next item on the loop.

Severity
7.8 (High)

Strategy: Language Selection

Choose a language that provides automatic memory management.

Mitigation
Implementation

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.
