Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux kernel是美国Linux基金会开源的操作系统Linux所使用的内核。 Linux kernel 6.19版本存在安全漏洞，该漏洞源于在airoha_qdma_init_tx_queue函数中ndesc初始化过早，当队列条目列表分配失败时，airoha_qdma_cleanup_tx_queue会访问队列条目数组导致空指针取消引用。
