Echo: linux: security update to 6.1.153-1

medium Tenable Self-Hosted Container Security Plugin ID 459861

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: serial: 8250: fix panic due to PSLVERR
 When the PSLVERR_RESP_EN parameter is set to 1, the device generates an error response if an attempt is
 made to read an empty RBR (Receive Buffer Register) while the FIFO is enabled. In serial8250_do_startup(),
 calling serial_port_out(port, UART_LCR, UART_LCR_WLEN8) triggers dw8250_check_lcr(), which invokes
 dw8250_force_idle() and serial8250_clear_and_reinit_fifos(). The latter function enables the FIFO via
 serial_out(p, UART_FCR, p->fcr). Execution proceeds to the serial_port_in(port, UART_RX). This satisfies
 the PSLVERR trigger condition. When another CPU (e.g., using printk()) is accessing the UART (UART is
 busy), the current CPU fails the check (value & ~UART_LCR_SPAR) == (lcr & ~UART_LCR_SPAR) in
 dw8250_check_lcr(), causing it to enter dw8250_force_idle(). Put serial_port_out(port, UART_LCR,
 UART_LCR_WLEN8) under the port->lock to fix this issue. Panic backtrace: [ 0.442336] Oops - unknown
 exception [#1] [ 0.442343] epc : dw8250_serial_in32+0x1e/0x4a [ 0.442351] ra :
 serial8250_do_startup+0x2c8/0x88e ... [ 0.442416] console_on_rootfs+0x26/0x70 (CVE-2025-39724)
