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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9858 vulnerabilities reference this CWE, most recent first.

Details

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

wifi: ath12k: fix htt mlo-offset event locking

The ath12k active pdevs are protected by RCU but the htt mlo-offset event handling code calling ath12k_mac_get_ar_by_pdev_id() was not marked as a read-side critical section.

Mark the code in question as an RCU read-side critical section to avoid any potential use-after-free issues.

Compile tested only.

Details

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PhantomPDF 9.5.0.20723. 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 removeField method when processing watermarks within AcroForms. 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 in conjunction with other vulnerabilities to execute code in the context of the current process. Was ZDI-CAN-8801.
