Echo: linux: security update to 6.1.153-1

medium Tenable Cloud Security Plugin ID 459039

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: media: rainshadow-cec: fix TOCTOU race
 condition in rain_interrupt() In the interrupt handler rain_interrupt(), the buffer full check on
 rain->buf_len is performed before acquiring rain->buf_lock. This creates a Time-of-Check to Time-of-Use
 (TOCTOU) race condition, as rain->buf_len is concurrently accessed and modified in the work handler
 rain_irq_work_handler() under the same lock. Multiple interrupt invocations can race, with each reading
 buf_len before it becomes full and then proceeding. This can lead to both interrupts attempting to write
 to the buffer, incrementing buf_len beyond its capacity (DATA_SIZE) and causing a buffer overflow. Fix
 this bug by moving the spin_lock() to before the buffer full check. This ensures that the check and the
 subsequent buffer modification are performed atomically, preventing the race condition. An corresponding
 spin_unlock() is added to the overflow path to correctly release the lock. This possible bug was found by
 an experimental static analysis tool developed by our team. (CVE-2025-39713)

Solution

Update the linux library and its related packages to version 6.1.153-1 or later.
