Common Weakness Enumeration
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
10962 vulnerabilities reference this CWE, most recent first.

Title
Use-after-free in Linux kernel's netfilter: nf_tables component
Summary
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.
The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error which resembles NF_ACCEPT.
We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660.

Title
Use-after-free in Linux kernel's netfilter: nf_tables component
Summary
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.
The nft_setelem_catchall_deactivate() function checks whether the catch-all set element is active in the current generation instead of the next generation before freeing it, but only flags it inactive in the next generation, making it possible to free the element multiple times, leading to a double free vulnerability.
We recommend upgrading past commit b1db244ffd041a49ecc9618e8feb6b5c1afcdaa7.

Title
Mali GPU Kernel Driver allows improper GPU memory processing operations
Summary
Use After Free vulnerability in Arm Ltd Bifrost GPU Kernel Driver, Arm Ltd Valhall GPU Kernel Driver, Arm Ltd Arm 5th Gen GPU Architecture Kernel Driver allows a local non-privileged user to make improper GPU memory processing operations. On Armv8.0 cores, there are certain combinations of the Linux Kernel and Mali GPU kernel driver configurations that would allow the GPU operations to affect the userspace memory of other processes.
This issue affects Bifrost GPU Kernel Driver: from r41p0 through r47p0; Valhall GPU Kernel Driver: from r41p0 through r47p0; Arm 5th Gen GPU Architecture Kernel Driver: from r41p0 through r47p0.

Title
Kernel: use-after-free while changing the mount option in __ext4_remount leading
Summary
A use-after-free flaw was found in the __ext4_remount in fs/ext4/super.c in ext4 in the Linux kernel. This flaw allows a local user to cause an information leak problem while freeing the old quota file names before a potential failure, leading to a use-after-free.

Title
Kernel: use-after-free after removing device in wb_inode_writeback_end in mm/page-writeback.c
Summary
A use-after-free flaw was found in the Linux Kernel. When a disk is removed, bdi_unregister is called to stop further write-back and waits for associated delayed work to complete. However, wb_inode_writeback_end() may schedule bandwidth estimation work after this has completed, which can result in the timer attempting to access the recently freed bdi_writeback.

Title
Packagekitd: use-after-free in idle function callback
Summary
A use-after-free flaw was found in PackageKitd. In some conditions, the order of cleanup mechanics for a transaction could be impacted. As a result, some memory access could occur on memory regions that were previously freed. Once freed, a memory region can be reused for other allocations and any previously stored data in this memory region is considered lost.

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.
