Common Weakness Enumeration

CWE-416

Allowed

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9839 vulnerabilities reference this CWE, most recent first.

GHSA-487W-XX5J-GQWC

Vulnerability from github – Published: 2025-04-29 12:30 – Updated: 2025-06-20 21:32
VLAI
Details

When DNSdist is configured to provide DoH via the nghttp2 provider, an attacker can cause a denial of service by crafting a DoH exchange that triggers an illegal memory access (double-free) and crash of DNSdist, causing a denial of service.

The remedy is: upgrade to the patched 1.9.9 version.

A workaround is to temporarily switch to the h2o provider until DNSdist has been upgraded to a fixed version.

We would like to thank Charles Howes for bringing this issue to our attention.

GHSA-48PQ-57C2-69WW

Vulnerability from github – Published: 2025-09-05 18:31 – Updated: 2025-11-25 18:32
VLAI
Details

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

open_tree_attr: do not allow id-mapping changes without OPEN_TREE_CLONE

As described in commit 7a54947e727b ('Merge patch series "fs: allow changing idmappings"'), open_tree_attr(2) was necessary in order to allow for a detached mount to be created and have its idmappings changed without the risk of any racing threads operating on it. For this reason, mount_setattr(2) still does not allow for id-mappings to be changed.

However, there was a bug in commit 2462651ffa76 ("fs: allow changing idmappings") which allowed users to bypass this restriction by calling open_tree_attr(2) without OPEN_TREE_CLONE.

can_idmap_mount() prevented this bug from allowing an attached mountpoint's id-mapping from being modified (thanks to an is_anon_ns() check), but this still allows for detached (but visible) mounts to have their be id-mapping changed. This risks the same UAF and locking issues as described in the merge commit, and was likely unintentional.

For this reason,\nmount_setattr(2) still does not allow for id-mappings to be changed.\n\nHowever, there was a bug in commit 2462651ffa76 (\"fs: allow changing\nidmappings\") which allowed users to bypass this restriction by calling\nopen_tree_attr(2) *without* OPEN_TREE_CLONE.\n\ncan_idmap_mount() prevented this bug from allowing an attached\nmountpoint\u0027s id-mapping from being modified (thanks to an is_anon_ns()\ncheck), but this still allows for detached (but visible) mounts to have\ntheir be id-mapping changed. This risks the same UAF and locking issues\nas described in the merge commit, and was likely unintentional.",

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.
