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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9854 vulnerabilities reference this CWE, most recent first.

Details

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

drm/xe/pf: Fix sysfs initialization

In case of devm_add_action_or_reset() failure the provided cleanup action will be run immediately on the not yet initialized kobject. This may lead to errors like:

[ ] kobject: '(null)' (ff110001393608e0): is not initialized, yet kobject_put() is being called. [ ] WARNING: lib/kobject.c:734 at kobject_put+0xd9/0x250, CPU#0: kworker/0:0/9 [ ] RIP: 0010:kobject_put+0xdf/0x250 [ ] Call Trace: [ ] xe_sriov_pf_sysfs_init+0x21/0x100 [xe] [ ] xe_sriov_pf_init_late+0x87/0x2b0 [xe] [ ] xe_sriov_init_late+0x5f/0x2c0 [xe] [ ] xe_device_probe+0x5f2/0xc20 [xe] [ ] xe_pci_probe+0x396/0x610 [xe] [ ] local_pci_probe+0x47/0xb0

Fix that by calling kobject_init() and kobject_add() separately and register cleanup action after the kobject is initialized.

Also make this cleanup registration a part of the create helper to fix another mistake, as in the loop we were wrongly passing parent kobject while registering cleanup action, and this resulted in some undetected leaks.

(cherry picked from commit 98b16727f07e26a5d4de84d88805ce7ffcfdd324)

Subversion's mod_dav_svn is vulnerable to memory corruption. While looking up path-based authorization rules, mod_dav_svn servers may attempt to use memory which has already been freed. Affected Subversion mod_dav_svn servers 1.10.0 through 1.14.1 (inclusive). Servers that do not use mod_dav_svn are not affected.

A use-after-free in BigIntPrimitive addition in Hermes prior to commit a6dcafe6ded8e61658b40f5699878cd19a481f80 could have been used by an attacker to leak raw data from Hermes VM’s heap. Note that this is only exploitable in cases where Hermes is used to execute untrusted JavaScript. Hence, most React Native applications are not affected.

smb: client: fix use-after-free bug in cifs_debug_data_proc_show()

Skip SMB sessions that are being teared down (e.g. @ses->ses_status == SES_EXITING) in cifs_debug_data_proc_show() to avoid use-after-free in @ses.

This fixes the following GPF when reading from /proc/fs/cifs/DebugData while mounting and umounting

Details

A flaw use after free in the Linux kernel Management Component Transport Protocol (MCTP) subsystem was found in the way user triggers cancel_work_sync after the unregister_netdev during removing device. A local user could use this flaw to crash the system or escalate their privileges on the system. It is actual from Linux Kernel 5.17-rc1 (when mctp-serial.c introduced) till 5.17-rc5.

GHSA-C429-FC87-8669

Vulnerability from github – Published: 2022-05-13 01:33 – Updated: 2022-05-13 01:33
VLAI
Details

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader 9.2.0.9297. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the handling of the boundItem method of a TimeField. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-6484.

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.
