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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9903 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2025-10-07 18:31 – Updated: 2026-06-01 18:31

Details

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

blk-mq: use quiesced elevator switch when reinitializing queues

The hctx's run_work may be racing with the elevator switch when reinitializing hardware queues. The queue is merely frozen in this context, but that only prevents requests from allocating and doesn't stop the hctx work from running. The work may get an elevator pointer that's being torn down, and can result in use-after-free errors and kernel panics (example below). Use the quiesced elevator switch instead, and make the previous one static since it is now only used locally.

Vulnerability from github – Published: 2024-12-27 15:31 – Updated: 2025-01-06 21:30
VLAI
Details

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

drm/xe/reg_sr: Remove register pool

That pool implementation doesn't really work: if the krealloc happens to move the memory and return another address, the entries in the xarray become invalid, leading to use-after-free later:

BUG: KASAN: slab-use-after-free in xe_reg_sr_apply_mmio+0x570/0x760 [xe]
Read of size 4 at addr ffff8881244b2590 by task modprobe/2753

Allocated by task 2753:
 kasan_save_stack+0x39/0x70
 kasan_save_track+0x14/0x40
 kasan_save_alloc_info+0x37/0x60
 __kasan_kmalloc+0xc3/0xd0
 __kmalloc_node_track_caller_noprof+0x200/0x6d0
 krealloc_noprof+0x229/0x380

Simplify the code to fix the bug. A better pooling strategy may be added back later if needed.

(cherry picked from commit e5283bd4dfecbd3335f43b62a68e24dae23f59e4)
