Echo: linux: security update to 6.1.180-1

medium Tenable Cloud Security Plugin ID 461835

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: iio: adc: lpc32xx: Initialize
 completion before requesting IRQ In the report from Jaeyoung Chung: "lpc32xx_adc_probe() in
 drivers/iio/adc/lpc32xx_adc.c registers its interrupt handler with devm_request_irq() before it
 initializes st->completion with init_completion(). If an interrupt arrives after devm_request_irq() and
 before init_completion(), the handler calls complete() on an uninitialized completion, causing a kernel
 panic. The probe path, in lpc32xx_adc_probe(): iodev = devm_iio_device_alloc(&pdev->dev, sizeof(*st)); /*
 st kzalloc-zeroed */ ... retval = devm_request_irq(&pdev->dev, irq, lpc32xx_adc_isr, 0, LPC32XXAD_NAME,
 st); /* register handler */ ... init_completion(&st->completion); /* initialize completion */
 lpc32xx_adc_isr() calls complete(): complete(&st->completion); If the device raises an interrupt before
 init_completion() runs, complete() acquires the uninitialized wait.lock and walks the zeroed task_list in
 swake_up_locked(). The zeroed task_list makes list_empty() return false, so swake_up_locked() dereferences
 a NULL list entry, triggering a KASAN wild-memory-access." Fix the chance of a spurious IRQ causing an
 uninitialized pointer dereference by moving init_completion() above devm_request_irq(). (CVE-2026-64500)

Solution

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