Memory Leak Issue in Linux Kernel's wl1251 Driver by Linux Foundation

CVE-2025-37982

What is CVE-2025-37982?

A vulnerability in the Linux kernel's wl1251 wireless driver has been identified that causes a memory leak when the wl1251_ps_elp_wakeup function fails due to a timeout error. This issue results in the skb (socket buffer) being dequeued from the tx_queue and subsequently lost. The proposed fix remedies this by ensuring the skb is correctly re-queued back to the tx_queue, enhancing the stability and reliability of network performance.
