Echo: linux: security update to 6.1.180-1

high Tenable Self-Hosted Container Security Plugin ID 463717

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: Input: touchwin - reset the packet
 index on every complete packet tw_interrupt() accumulates each non-zero serial byte into a fixed three-
 byte buffer with a running index that is only reset once a full packet has been received *and* the
 device's two Y bytes agree: tw->data[tw->idx++] = data; if (tw->idx == TW_LENGTH && tw->data[1] ==
 tw->data[2]) { ... tw->idx = 0; } The reset is gated on tw->data[1] == tw->data[2], a value the device
 controls. A malicious, malfunctioning or counterfeit Touchwindow peripheral can stream non-zero bytes
 whose 2nd and 3rd bytes differ: the index reaches TW_LENGTH without the equality holding, is never reset,
 and keeps growing, so tw->data[tw->idx++] walks off the end of the three-byte array and the rest of the
 heap-allocated struct tw, one attacker-chosen byte at a time -- an unbounded, device-driven heap out-of-
 bounds write. Reset the index on every completed packet and report an event only when the two Y bytes
 match, like the other serio touchscreen drivers do. (CVE-2026-64271)

Solution

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