Echo: linux: security update to 6.1.159-1

high Tenable Cloud Security Plugin ID 462133

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: ALSA: usb-audio: Fix potential
 overflow of PCM transfer buffer The PCM stream data in USB-audio driver is transferred over USB URB packet
 buffers, and each packet size is determined dynamically. The packet sizes are limited by some factors such
 as wMaxPacketSize USB descriptor. OTOH, in the current code, the actually used packet sizes are determined
 only by the rate and the PPS, which may be bigger than the size limit above. This results in a buffer
 overflow, as reported by syzbot. Basically when the limit is smaller than the calculated packet size, it
 implies that something is wrong, most likely a weird USB descriptor. So the best option would be just to
 return an error at the parameter setup time before doing any further operations. This patch introduces
 such a sanity check, and returns -EINVAL when the packet size is greater than maxpacksize. The comparison
 with ep->packsize[1] alone should suffice since it's always equal or greater than ep->packsize[0].
 (CVE-2025-40269)

Solution

Update the linux library and its related packages to version 6.1.159-1 or later.
