Echo: linux: security update to 6.1.170-1

medium Tenable Self-Hosted Container Security Plugin ID 459565

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: NFC: pn533: bound the UART receive
 buffer pn532_receive_buf() appends every incoming byte to dev->recv_skb and only resets the buffer after
 pn532_uart_rx_is_frame() recognizes a complete frame. A continuous stream of bytes without a valid PN532
 frame header therefore keeps growing the skb until skb_put_u8() hits the tail limit. Drop the accumulated
 partial frame once the fixed receive buffer is full so malformed UART traffic cannot grow the skb past
 PN532_UART_SKB_BUFF_LEN. (CVE-2026-43032)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
