Echo: linux: security update to 6.1.180-1

medium Tenable Self-Hosted Container Security Plugin ID 459749

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: net: usb: kalmia: bound RX frame
 length in kalmia_rx_fixup() kalmia_rx_fixup() computes usb_packet_length = skb->len - (2 *
 KALMIA_HEADER_LENGTH) as a u16, guarded only by a pre-loop check that skb->len is at least
 KALMIA_HEADER_LENGTH, which is 6. A device can deliver a short bulk-IN frame with skb->len in the 6 to 11
 range, or leave a short trailing remainder on a later loop iteration. Either case underflows
 usb_packet_length to about 65530. That bypasses the usb_packet_length < ether_packet_length truncation
 path. The device-supplied ether_packet_length, a le16 up to 65535 read from header_start[2], then drives a
 memcmp() and the following skb_trim() and skb_pull() past the end of the rx buffer. The rx buffer is
 hard_mtu * 10, which is 14000 bytes. That is an out of bounds read. Require both the start and end framing
 headers to be present before subtracting them, on every loop iteration. (CVE-2026-64351)

Solution

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