Echo: linux: security update to 6.1.147-1

medium Tenable Cloud Security Plugin ID 463641

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: wifi: zd1211rw: Fix potential NULL
 pointer dereference in zd_mac_tx_to_dev() There is a potential NULL pointer dereference in
 zd_mac_tx_to_dev(). For example, the following is possible: T0 T1 zd_mac_tx_to_dev() /* len ==
 skb_queue_len(q) */ while (len > ZD_MAC_MAX_ACK_WAITERS) { filter_ack() spin_lock_irqsave(&q->lock,
 flags); /* position == skb_queue_len(q) */ for (i=1; i<position; i++) skb = __skb_dequeue(q) if (mac->type
 == NL80211_IFTYPE_AP) skb = __skb_dequeue(q); spin_unlock_irqrestore(&q->lock, flags); skb_dequeue() ->
 NULL Since there is a small gap between checking skb queue length and skb being unconditionally dequeued
 in zd_mac_tx_to_dev(), skb_dequeue() can return NULL. Then the pointer is passed to zd_mac_tx_status()
 where it is dereferenced. In order to avoid potential NULL pointer dereference due to situations like
 above, check if skb is not NULL before passing it to zd_mac_tx_status(). Found by Linux Verification
 Center (linuxtesting.org) with SVACE. (CVE-2025-38513)

Solution

Update the linux library and its related packages to version 6.1.147-1 or later.
