Echo: linux: security update to 6.1.162-1

high Tenable Self-Hosted Container Security Plugin ID 459362

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: rsi: Fix memory corruption due
 to not set vif driver data size The struct ieee80211_vif contains trailing space for vif driver data, when
 struct ieee80211_vif is allocated, the total memory size that is allocated is sizeof(struct ieee80211_vif)
 + size of vif driver data. The size of vif driver data is set by each WiFi driver as needed. The RSI911x
 driver does not set vif driver data size, no trailing space for vif driver data is therefore allocated
 past struct ieee80211_vif . The RSI911x driver does however use the vif driver data to store its vif
 driver data structure "struct vif_priv". An access to vif->drv_priv leads to access out of struct
 ieee80211_vif bounds and corruption of some memory. In case of the failure observed locally,
 rsi_mac80211_add_interface() would write struct vif_priv *vif_info = (struct vif_priv *)vif->drv_priv;
 vif_info->vap_id = vap_idx. This write corrupts struct fq_tin member struct list_head new_flows . The flow
 = list_first_entry(head, struct fq_flow, flowchain); in fq_tin_reset() then reports non-NULL bogus
 address, which when accessed causes a crash. The trigger is very simple, boot the machine with
 init=/bin/sh , mount devtmpfs, sysfs, procfs, and then do "ip link set wlan0 up", "sleep 1", "ip link set
 wlan0 down" and the crash occurs. Fix this by setting the correct size of vif driver data, which is the
 size of "struct vif_priv", so that memory is allocated and the driver can store its driver data in it,
 instead of corrupting memory around it. (CVE-2026-23073)

Solution

Update the linux library and its related packages to version 6.1.162-1 or later.
