Echo: linux: security update to 6.1.162-1

high Tenable Self-Hosted Container Security Plugin ID 463477

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: dmaengine: tegra-adma: Fix use-after-
 free A use-after-free bug exists in the Tegra ADMA driver when audio streams are terminated, particularly
 during XRUN conditions. The issue occurs when the DMA buffer is freed by tegra_adma_terminate_all() before
 the vchan completion tasklet finishes accessing it. The race condition follows this sequence: 1. DMA
 transfer completes, triggering an interrupt that schedules the completion tasklet (tasklet has not
 executed yet) 2. Audio playback stops, calling tegra_adma_terminate_all() which frees the DMA buffer
 memory via kfree() 3. The scheduled tasklet finally executes, calling vchan_complete() which attempts to
 access the already-freed memory Since tasklets can execute at any time after being scheduled, there is no
 guarantee that the buffer will remain valid when vchan_complete() runs. Fix this by properly synchronizing
 the virtual channel completion: - Calling vchan_terminate_vdesc() in tegra_adma_stop() to mark the
 descriptors as terminated instead of freeing the descriptor. - Add the callback tegra_adma_synchronize()
 that calls vchan_synchronize() which kills any pending tasklets and frees any terminated descriptors.
