Echo: linux: security update to 6.1.180-1

medium Tenable Self-Hosted Container Security Plugin ID 457935

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: caiaq: fix out-of-bounds read in
the Traktor Kontrol S4 input parser snd_usb_caiaq_tks4_dispatch() decodes the Traktor Kontrol S4 input
stream in fixed 16-byte (TKS4_MSGBLOCK_SIZE) message blocks. On every iteration it advances buf and
subtracts the block size while looping on "while (len)". len is urb->actual_length. That value is supplied
by the device and is not guaranteed to be a multiple of 16. When a final short block leaves len between 1
and 15, the loop runs once more, reads up to buf[15], and then does "len -= TKS4_MSGBLOCK_SIZE". As len is
unsigned this underflows to a huge value. The loop then keeps iterating and walking buf far past the end
of the 512-byte ep4_in_buf, reading out of bounds until a bogus block id happens to be hit. Iterate only
while a full message block is available. This stops the unsigned underflow and silently drops any trailing
partial block, which carries no complete control value anyway. The sibling endpoint-4 parsers are not
affected. The Traktor Kontrol X1 and Maschine arms in snd_usb_caiaq_ep4_reply_dispatch() floor
urb->actual_length before dispatching. (CVE-2026-64487)

Solution

Update the linux library and its related packages to version 6.1.180-1 or later.
