fkie_cve-2025-21715

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

net: davicom: fix UAF in dm9000_drv_remove

dm is netdev private data and it cannot be used after free_netdev() call. Using dm after free_netdev() can cause UAF bug. Fix it by moving free_netdev() at the end of the function.

This is similar to the issue fixed in commit ad297cd2db89 ("net: qcom/emac: fix UAF in emac_remove").

This bug is detected by our static analysis tool.

OESA-2025-1339 — kernel security update

Affected: openEuler:24.03-LTS: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

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

dma-debug: fix a possible deadlock on radix_lock

radix_lock() shouldn't be held while holding dma_hash_entry[idx].lock otherwise, there's a possible deadlock scenario when dma debug API is called holding rq_lock():

CPU0 CPU1 CPU2 dma_free_attrs() check_unmap() add_dma_entry() __schedule() //out (A) rq_lock() get_hash_bucket() (A) dma_entry_hash check_sync() (A) radix_lock() (W) dma_entry_hash dma_entry_free() (W) radix_lock() // CPU2's one (W) rq_lock()

CPU1 situation can happen when it extending radix tree and it tries to wake up kswapd via wake_all_kswapd().

CPU2 situation can happen while perf_event_task_sched_out() (i.e. dma sync operation is called while deleting perf_event using etm and etr tmc which are Arm Coresight hwtracing driver backends).

To remove this possible situation, call dma_entry_free() after put_hash_bucket() in check_unmap().(CVE-2024-47143)
